Tainan enjoys a tropical monsoon climate with distinct wet and dry seasons that'll shape your visit quite a bit. The city experiences warm to hot temperatures year-round, with winter months (December through February) being pleasantly mild—highs around 23-24°C (73-75°F)—while summer (June through August) cranks up the heat to around 32-33°C (90-91°F). What really defines the seasons here isn't so much temperature as rainfall: you'll find a dramatic difference between the bone-dry winter months and the absolutely drenching summer monsoon season. The rainfall pattern is pretty striking, actually. From October through April, Tainan stays relatively dry with monthly rainfall under 70mm (2.7 inches), making it quite comfortable for wandering around the city's temples and historic sites. Then May kicks off the wet season, and by June through August, you're looking at serious rainfall—up to 480mm (18.9 inches) in August. These aren't necessarily all-day rains, but when they come, they tend to be intense. Humidity hovers around 70% throughout the year, which means even the cooler months feel a bit sticky, and summer can feel properly steamy. Worth noting that typhoon season runs from July through September, so there's always a chance of more dramatic weather during those months.

Best Time to Visit

Beach & Relaxation
April through May or September through October offer the sweet spot—warm enough for beach weather (27-32°C/81-90°F) but before or after the heaviest monsoon rains and typhoon risks.
Cultural Exploration
November through March is ideal for temple-hopping and exploring historic districts, with comfortable temperatures (23-26°C/73-79°F), minimal rainfall, and pleasant conditions for walking around all day.
Adventure & Hiking
October through April provides the most reliable weather for outdoor activities, with lower rainfall and temperatures that won't leave you completely drenched in sweat on the trails.
Budget Travel
June through August sees fewer tourists due to the heavy rains and heat, which typically means better deals on accommodation, though you'll need to be flexible with weather-dependent plans.

What to Pack

Year-Round Essentials

High SPF sunscreen
The subtropical sun is intense year-round, and you'll burn faster than you think even on overcast days.
Compact umbrella
Useful both as rain protection during wet season and as a sun shade during the scorching summer months.
Moisture-wicking clothing
With 70% humidity year-round, fabrics that dry quickly and breathe well make a huge difference in comfort.
Portable fan or cooling towel
The heat and humidity can be intense, especially when exploring temples and outdoor markets.
Reusable water bottle
Staying hydrated is crucial in Tainan's climate, and there are plenty of places to refill.
Insect repellent
Mosquitoes are present year-round but especially active during and after the rainy season.
Day pack with waterproof cover
You'll want something for carrying essentials while temple-hopping, and keeping things dry is always wise.

Light cotton or linen shirts, Breathable shorts or skirts, Light rain jacket for May showers
Footwear

Footwear
Comfortable walking shoes as rainfall decreases and you'll be doing more exploring

Skip These Items

Heavy winter clothing or thick jackets Hair dryer (most hotels provide them, and the humidity makes styling difficult anyway) Large quantities of toiletries (7-Eleven and drugstores are everywhere with affordable options) Beach towels (available at beaches or your accommodation) Formal shoes (Tainan is quite casual, and you'll want comfort over style for all the walking)

June

June kicks off the full monsoon season with substantial rainfall—around 368mm (14.5 inches) for the month.

July

July brings the year's hottest temperatures at 33°C (91°F) along with heavy monsoon rains. This is also the start of typhoon season, which can bring dramatic weather systems through the region.
