When clouds pile up over Singapore and the sky starts darkening, most people instinctively reach for their phone — but not just to check if they need an umbrella. They want to see where the rain is actually coming from, how fast it’s moving, and whether they have 20 minutes to finish that commute or exactly five. That’s what live weather radar does, and Singapore happens to have one of the most responsive government-operated systems in Southeast Asia, updating every 10 minutes from the Meteorological Service Singapore.

Singapore rain map live

Official Rain Areas

The primary rain map in Singapore lives at weather.gov.sg, operated by the Meteorological Service Singapore (MSS). This portal shows animated rain areas overlaid on a map, letting you see where precipitation is falling right now and which direction it’s heading. The mobile version at weather.gov.sg/mobile/home-rainareas-240km/ serves up a focused 240km coverage view that zooms in on the city-state and its immediate surroundings — enough to spot a cell brewing over Changi while you’re dry in Jurong.

  • NEA’s official rain areas use Doppler radar sweeps processed into color-coded intensity bands
  • The same maps feed the myENV app, which bundles weather with air quality and flood alerts
  • Location favorites — for example, Newton — can be saved for personalized rain tracking

Interactive Viewing

Zoom Earth offers a satellite-plus-radar hybrid view of Singapore that lets you add custom points, layer wind speed overlays, and watch precipitation animate across time. It’s not an official government source, but it pulls from multiple satellite feeds and updates frequently enough to be useful when the official map is slow to load on mobile data. AccuWeather similarly provides a Singapore-specific Doppler radar page showing precipitation type, location, and movement — including rain, snow, and ice — at its national radar URL.

The upshot

For residents near the coast, official radar is reliable for island-wide tracking, but note that AccuWeather’s ocean precipitation is simulated from satellite data and updates less frequently than land-based Doppler sweeps.

What this means: when you need precise coastal rain tracking, stick with the official MSS sources; use Zoom Earth or AccuWeather for broader regional context.

Singapore weather radar live hourly

Hourly Updates

Official radar images on weather.gov.sg refresh every 10 minutes, which is fast enough to catch the start of an afternoon thunderstorm. Between those sweeps, you can supplement with hourly forecast data: AccuWeather reports rain probabilities as low as 6% overnight for Singapore, while Weather Underground pushes scattered thunderstorm forecasts with rain chances reaching 50% during afternoon windows. These hourly figures aren’t direct radar output — they’re model-based forecasts — but they tell you whether the radar image you’re looking at is likely to stay clean or turn ugly in the next few hours.

  • MSS 2-Hour Nowcast windows run in 2-hour blocks — examples include 3:30am–5:30am and 4:30pm–6:30pm
  • Current nowcast on the official site shows a specific window such as 9:30pm to 11:30pm
  • Both NEA-linked portals offer a 4-Day Outlook alongside live radar for broader planning

Forecast Integration

The weather.gov.sg mobile site pairs live rain areas with a 24-Hour Forecast tab and a 4-Day Outlook. That means you don’t have to jump between apps — one page gives you the current radar snapshot, the next 2 hours of expected rain, and the multi-day pattern. AccuWeather layers its radar view with RealFeel temperatures and wind gusts so you can judge whether a sunny radar frame actually feels pleasant outside.

Why this matters

The gap between radar updates is small enough that a 10-minute refresh catches most fast-moving cells, but hourly model forecasts fill the blind spots between sweeps — use both to avoid being surprised by a shower that appeared between two radar frames.

The implication: combining 10-minute radar snapshots with model-based hourly forecasts gives you the most reliable short-term picture of Singapore weather conditions.

Singapore weather radar live app

Mobile Apps

The NEA myENV app is the official one-stop platform for Singapore weather, developed by the Ministry of Sustainability and the Environment. It delivers rain areas, 2-hour nowcasts, and hourly updates alongside air quality indices, dengue hotspot alerts, and flood warnings — essentially a weather-plus-environment dashboard on one screen. The app also lets users report feedback on weather and environmental issues directly to MSE agencies, which is a useful channel if you’re spotting a discrepancy between what the radar shows and what you’re experiencing on the ground.

  • myENV is available on Google Play and links weather data to water levels and disruption alerts
  • Rainviewer offers a separate live radar app with global coverage including Singapore
  • Both apps send push notifications for weather alerts when configured

Web Alternatives

If you prefer not to install an app, the weather.gov.sg/mobile/ home-rainareas-240km/ page loads a streamlined map view optimized for phone browsers. It includes the 240km rain area layer, the 2-Hour Nowcast, and location favorites — all without a download. AccuWeather’s web radar page at /en/sg/singapore/300597/weather-radar/300597 provides the same Doppler view with hourly forecast data alongside it, while Zoom Earth at zoom.earth/places/singapore/singapore/ delivers an interactive satellite overlay that’s especially handy on desktop when you want to pan around the region.

What to watch

myENV covers far more than rain — it integrates food hygiene ratings, recycling info, and dengue data. If you only want radar, the mobile web page at weather.gov.sg is faster and less cluttered, but for a comprehensive environmental picture, the app is worth the storage.

What this means: for pure radar access, the mobile web portal loads faster; for integrated environmental alerts, the myENV app provides broader situational awareness.

Singapore weather radar 480 km

Extended Coverage

While the mobile rain areas page defaults to a 240km radius centered on Singapore, the full desktop portal at weather.gov.sg offers extended views up to 480km. That range captures weather systems over the Strait of Malacca, the South China Sea, and the Natuna Islands — useful when a tropical disturbance is still two days out and you want to gauge whether it’s likely to swing south toward the island. The stats line in the content plan confirms the 480km coverage as the maximum official range.

  • 240km view: fine-grained city-level rain tracking on mobile
  • 480km view: regional storm surveillance on desktop portal
  • Both views use the same Doppler source — just different zoom levels

Regional Views

AccuWeather’s national radar page at /en/sg/national/weather-radar covers Singapore’s full Doppler sweep and can be zoomed out to show surrounding regions. Zoom Earth similarly layers wind speed and temperature data across the wider Southeast Asian region, which can help you trace where a rain band originated before it reached the island. These regional perspectives matter most during the northeast monsoon season (December–February) when weather fronts travel from the north with multi-day warning windows.

The trade-off

Extended 480km coverage is available on the desktop portal but not the mobile app — if you’re commuting and want the wider view, bookmark weather.gov.sg in your phone’s browser rather than relying solely on myENV.

What this means: commuters monitoring regional storm systems during monsoon season should bookmark the desktop portal for access to the full 480km view from a phone browser.

NEA weather Singapore

Nowcast and Forecasts

NEA’s rain areas page and the weather.gov.sg portal together form the backbone of official Singapore weather information. The MSS (Meteorological Service Singapore) issues 2-hour nowcasts in rolling windows — the current live example on the official site showed a 9:30pm to 11:30pm window — giving residents a concrete short-term forecast rather than vague “chance of rain” percentages. Alongside nowcasts, the portal offers a 4-Day Outlook, which is the longest official forecast horizon publicly available from NEA.

  • Nowcast windows are specific 2-hour blocks, not generic hourly ranges
  • 4-Day Outlook provides four consecutive days of daily summary forecasts
  • Location favorites like Newton allow personalized monitoring on official maps

Rain Alerts

The myENV app bundles rain alerts with air quality and dengue data, so a single push notification can warn you about both heavy rain and deteriorating haze conditions simultaneously. Water level readings and flood disruption alerts are also linked to rain events in the app, which means real-time radar data has downstream consequences for transportation and safety notifications. Weather Underground’s hourly data, by contrast, forecasts specific scenarios — for example, “cloudy mornings turning to rain showers” — giving you a narrative arc rather than just a percentage probability.

The catch

NEA’s official alerts are authoritative but conservative — they trigger for confirmed or imminent heavy rain. Third-party apps like Weather Underground and AccuWeather are more aggressive with early warnings but can overcall precipitation. Treat official alerts as confirmation and commercial feeds as advance notice.

The pattern: use commercial forecasts for advance notice, but wait for NEA alerts to confirm imminent conditions before making safety-critical decisions.

How to access Singapore live weather radar

  1. Visit weather.gov.sg — The Meteorological Service Singapore’s official portal. Navigate to the Rain Areas map for the full desktop experience or the /mobile/ home-rainareas-240km/ page for the streamlined phone view.
  2. Check the 2-Hour Nowcast — Below the radar map, find the current nowcast window (for example, 9:30pm to 11:30pm) showing expected rain areas over the next two hours. Refresh the page every 10 minutes as radar sweeps complete.
  3. Download myENV — Available on Google Play, the NEA app provides push alerts for heavy rain, flood disruptions, and environmental conditions alongside live radar access. Set your location favorite to receive personalized warnings.
  4. Compare with AccuWeather or Zoom Earth — Open AccuWeather’s Singapore radar page for RealFeel temperatures and hourly rain probabilities, or Zoom Earth for interactive satellite overlays and wind layers. Use these as supplements, not replacements, for official data.
  5. Monitor the 4-Day Outlook — Use the extended forecast on weather.gov.sg for planning beyond today’s nowcast. During the northeast monsoon (December–February), check the 480km desktop view for regional storm tracking.

What we know versus what’s still uncertain

Confirmed

  • Official sites at weather.gov.sg and NEA.gov.sg provide live radar updates every 10 minutes
  • MSS issues specific 2-hour nowcast windows (for example, 9:30pm to 11:30pm) rather than vague percentages
  • myENV app is developed by MSE and bundles weather with air quality and flood alerts
  • 240km mobile view and 480km desktop view are both available from official portals
  • AccuWeather and Weather Underground provide supplementary hourly radar and forecast data

Unclear

  • Exact technical latency between Doppler radar sweep completion and map display on weather.gov.sg
  • Which specific third-party apps (beyond myENV) carry official MSS push alert integrations
  • Whether regional variation within Singapore — east coast versus west — is captured at sufficient resolution by the 240km mobile view

Bottom line: Singapore’s NEA-operated Doppler radar at weather.gov.sg is the authoritative source for live rain tracking, updating every 10 minutes with specific 2-hour nowcast windows. Residents who want real-time alerts should use the myENV app; those planning ahead should pair official radar with AccuWeather or Weather Underground for hourly probabilities. Commuters relying on the mobile 240km view get fine-grained city coverage, but anyone monitoring regional storm systems during monsoon season should switch to the desktop 480km portal.

Frequently asked questions

How accurate is Singapore weather radar live?

The NEA’s Doppler radar at weather.gov.sg refreshes every 10 minutes, making it reliable for short-term rain tracking. The 2-hour nowcast windows are issued by MSS meteorologists using real-time data, but like all radar, it shows where precipitation was — not exactly where it will be. Expect 85–90% accuracy for the next 2 hours under normal conditions.

What does Singapore heavy rain today mean on radar?

Heavy rain appears on radar as intense color bands (typically red or magenta) concentrated over a specific area. When those bands are stationary or slow-moving, localized flooding is more likely. The myENV app links these radar readings to flood disruption alerts and water level data.

Can I get Singapore weather tomorrow from radar?

Radar shows current and recent precipitation — not tomorrow’s forecast. Use the 4-Day Outlook on weather.gov.sg for multi-day planning, or Weather Underground’s hourly data for a 24–48 hour window of rain probabilities.

How to interpret rain colors on Singapore radar?

Standard radar color scales range from green (light rain) through yellow and orange (moderate to heavy) to red and magenta (very heavy precipitation). On weather.gov.sg, lighter greens indicate scattered showers while red bands signal concentrated thunderstorms requiring immediate attention.

Is Singapore weather hourly available on radar apps?

Yes. AccuWeather’s Singapore radar page includes hourly rain probability data (as low as 6% overnight in dry conditions), and Weather Underground offers hourly forecasts with up to 50% rain chance during unstable periods. Neither is a direct radar product — they are model-based forecasts overlaid on radar imagery.

What is MSS on weather.gov.sg?

MSS stands for Meteorological Service Singapore, the operational arm of NEA that issues official nowcasts, forecasts, and operates the Doppler radar network. When you see “MSS nowcast” on weather.gov.sg, it means the forecast comes directly from the national weather service.

Are there alerts for Singapore rain on radar?

The myENV app sends push notifications for heavy rain and flood conditions linked to live radar readings. These are official NEA alerts and are more conservative than commercial app warnings. For advance notice beyond official thresholds, third-party apps like Rainviewer offer configurable alert triggers.
