Month-by-Month Guide
January
January brings Tainan's coolest weather, though "cool" is relative—you're still looking at pleasant 23°C (73°F) days. It's the driest month of the year with minimal rainfall, making it perfect for exploring the city's outdoor attractions. This is peak tourist season, so expect more crowds at popular sites but generally excellent weather for sightseeing.
February
February stays comfortably mild and dry, with temperatures creeping up just slightly from January. The Lunar New Year often falls in this month, which means vibrant celebrations throughout Tainan but also means many local businesses close for the holiday. It's still very much peak season with excellent weather for outdoor activities and cultural exploration.
March
March marks the beginning of spring with warming temperatures that reach 26°C (79°F) but still relatively low rainfall. The weather remains quite comfortable for all-day exploration, and you'll start seeing more local festivals and outdoor events. Humidity stays consistent, but the temperatures haven't yet reached the intense summer heat.
April
April brings noticeably warmer weather with highs around 29°C (84°F), and you'll start to see rainfall picking up a bit—though it's still quite manageable. This is actually a lovely time to visit, as temperatures are warm enough for beach activities but haven't reached the oppressive summer heat. The shoulder season means fewer crowds than winter months.
May
May is when things start shifting toward summer conditions—temperatures climb to 31°C (88°F) and rainfall more than doubles from April. You'll likely encounter some heavy afternoon thunderstorms, though they tend to be brief. The heat becomes more intense, and combined with the humidity, it can feel quite sticky during midday hours.
June
June kicks off the full monsoon season with substantial rainfall—around 368mm (14.5 inches) for the month. Temperatures hover around 32°C (90°F), and the combination of heat, humidity, and frequent heavy rains makes this challenging for extensive outdoor activities. That said, the rain often comes in intense bursts rather than all-day drizzle, so you can still plan around it.
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. Tourist numbers drop significantly, and honestly, unless you're specifically chasing summer festivals or don't mind the heat and wet conditions, it's not the most comfortable time to visit.
August
August is typically the wettest month of the year with nearly 480mm (18.9 inches) of rainfall, and typhoon risk remains elevated. Temperatures stay around 32°C (90°F), and the combination of intense heat and heavy rains creates pretty steamy conditions. Many travelers avoid this month, which means great deals on accommodation if you're willing to be flexible with your plans.
September
September maintains summer heat at 32°C (90°F) but rainfall starts to decrease noticeably from the August peak. Typhoon season continues through this month, so there's still some weather uncertainty. The tail end of September can actually be quite pleasant as conditions begin transitioning toward the drier, more comfortable autumn months.
October
October marks a welcome shift as rainfall drops dramatically to just 25mm (1.0 inch) and temperatures become more comfortable at 31°C (87°F). This is when Tainan's weather really starts to shine—warm enough for outdoor activities but without the oppressive summer heat and constant rain. It's an excellent shoulder season month with fewer tourists and reliable weather.
November
November offers some of Tainan's most pleasant weather conditions—temperatures cool to a comfortable 28°C (82°F), rainfall stays minimal, and humidity feels less oppressive than summer months. This is prime time for exploring the city's temples, night markets, and historic sites without battling heat or rain. Tourist numbers start picking up as word gets out about the excellent weather.
December
December brings the coolest temperatures of the year with highs around 24°C (75°F) and the absolute lowest rainfall. The weather is genuinely lovely for sightseeing—you might even want a light jacket for evening strolls. This is peak tourist season for good reason, as conditions are about as comfortable as they get in subtropical Tainan.
