Five key figures capture the December climate at a glance. The table below pulls together the most practical numbers for trip planning.

Is December good to visit New Zealand?

The short answer is yes – but with caveats. December brings warm summer weather and a festive atmosphere, yet it’s also the start of the most expensive and crowded period of the year. Here’s how the pros and cons stack up.

Pros of visiting in December

Cons of visiting in December

The implication: December works best for those who can book early and budget for premium pricing. The catch is that spontaneous travel becomes difficult – plan at least three months ahead.

How cold is it in New Zealand in December?

“Cold” isn’t the word most travelers use. December means early summer, but temperatures vary noticeably by region.

Average December temperatures by region

• North Island (Auckland, Bay of Islands): Daytime highs 23–25°C (73–77°F); nights 12–15°C (54–59°F) – warm and often humid.
• Central North Island (Taupo, Rotorua): Highs 21–23°C (70–73°F); cooler at night, around 10°C (50°F).
• Upper South Island (Nelson, Marlborough): Highs 22–24°C (72–75°F) – one of the sunniest areas.
• Lower South Island (Queenstown, Dunedin): Highs 18–21°C (64–70°F); nights 8–10°C (46–50°F).
• West Coast (Franz Josef, Fox Glacier): Highs 18–20°C (64–68°F); high rainfall even in December.

These figures come from historical climate data published by 100% Pure New Zealand (official tourism site) and kimkim (travel planning platform).

What to pack for New Zealand in December

• Lightweight clothing (shorts, t-shirts, dresses) for daytime
• Warmer layers (fleece, light sweater) for evenings and South Island
• Waterproof jacket – essential even on “dry” days (100% Pure New Zealand (official tourism site))
• Comfortable walking shoes and sandals
• Sun hat, sunglasses, and high-SPF sunscreen – UV levels are intense in summer
• Swimwear for beaches and hot pools

The pattern is clear: December is warm but not scorching. The hottest months – January and February – arrive later (100% Pure New Zealand (official tourism site)).

Is New Zealand cheap in December?

Generally, no. December sits firmly in the high season. Accommodation prices can double compared to the shoulder months.

Peak season pricing

kimkim (travel planning platform) notes that flights, rental cars, and campsites all command a premium. The Interislander Ferry is a specific bottleneck – book weeks ahead.

Tips to save money in December

• Book flights and accommodation at least 2–3 months in advance to lock in lower rates.
• Travel in the first half of December before schools close (mid-to-late December).
• Consider self-catering accommodation (holiday parks, Airbnbs) to save on meals.
• Use public transport or shuttle services instead of rental cars in busy areas.

The catch: even with early booking, expect to pay 20–40% more than in October or April. For budget travelers, shoulder months offer better value.

What is the wettest month in New Zealand?

July is the wettest month nationwide (100% Pure New Zealand (official tourism site)). But December’s rainfall varies dramatically by region.

Rainfall patterns in December

• Auckland and Northland: relatively dry – among the lowest rainfall months (kimkim (travel planning platform)).
• Wellington and lower North Island: moderate rainfall, occasional showers.
• West Coast of South Island: some of the highest December rainfall in the country – expect rain on more than half the days.
• Queenstown, Dunedin, Invercargill: December is actually their wettest month overall (kimkim (travel planning platform)).

Regional differences in precipitation

The contrast is stark. Auckland averages 75 mm of rain in December, while Queenstown gets about 55 mm – but the West Coast can see 150 mm or more.

The pattern: if you’re heading to the South Island’s west, pack extra waterproofs. In the north, you’ll likely enjoy fine, settled weather with the odd shower.

What is the best month to go to New Zealand?

There’s no single answer – it depends on what you want. But December holds a unique appeal for summer lovers willing to pay for it.

Summer months (December–February)

• Best for beaches, hiking, kayaking, and outdoor festivals.
• Peak crowds and highest prices.
• Longest daylight hours (up to 15 hours in December).

Shoulder seasons (March–May, September–November)

• Milder weather, fewer tourists, lower costs.
• March–April is autumn – beautiful fall colors and settled weather.
• September–November is spring – blooming landscapes, quieter trails.

Winter months (June–August)

• Ski season – best for snow sports in Queenstown, Wanaka, and Ruapehu.
• Coldest month is July (100% Pure New Zealand (official tourism site)).
• Lower prices on non-ski accommodation and flights.

Why this matters: December offers the best summer conditions but at a premium. For travelers with flexible dates, the shoulder months deliver 90% of the experience at 60% of the cost.

What’s clear and what’s not

Confirmed facts:

• December is summer in New Zealand.
• Average daytime temperatures range 20–25°C.
• December is part of the most expensive travel season.
• July is the wettest and coldest month.

What remains unclear:

• Exact hourly weather for December 2025 – long-term forecasts are not yet available.
• Specific rainfall totals for every small town – variability is high year to year.

What travelers are saying

“December is the start of summer in New Zealand, with daytime temperatures averaging 20–25°C. It’s a fantastic time for outdoor activities, but visitors should always pack a raincoat because showers can happen at any time.”
