Taiwan Weather Seasons

Spring in Taiwan: March to May

Spring is one of the most comfortable times to travel around Taiwan. Temperatures gradually become warmer, flowers start blooming, and outdoor sightseeing is usually easier than during the hotter summer months.

Typical spring temperatures are generally around 18°C to 25°C, although northern areas and mountains can be cooler.

What to expect:

• Mild daytime temperatures
• Cooler mornings and evenings
• Flowers and cherry blossoms in some areas
• Increasing humidity
• More rain toward May
• Good weather for walking and hiking

Best places to visit: Taipei, Taichung, Sun Moon Lake, Alishan, Jiufen, and Tainan.

🌸 Travel Tip: Bring a light jacket or cardigan, especially if you are visiting northern Taiwan or mountain areas. Keep a small umbrella in your bag as spring weather can change quickly.

Taiwan Plum Rain Season: May to June

Late spring to early summer brings the Mei-Yu or plum rain season.

During this period, weather fronts can bring several days of rain, thunderstorms, or occasionally very heavy rainfall. Taiwan's Central Weather Administration normally sees the summer monsoon beginning around the middle of May, although the timing changes from year to year.

What to expect:

• Frequent rain
• Cloudy skies
• High humidity
• Sudden heavy showers
• Possible thunderstorms
• Slippery hiking trails

This does not mean it rains the whole day every day. You can still travel, but keeping your itinerary flexible is important.

☔ Travel Tip: Schedule outdoor attractions in the morning and keep malls, museums, cafes, hot springs, and shopping areas as backup plans.

Summer in Taiwan: June to August

Summer is the hottest and most humid season in Taiwan.

Temperatures commonly reach around 26°C to 34°C, and some cities can feel even hotter because of the humidity.

What to expect:

• Hot afternoons
• Strong sunshine
• High humidity
• Afternoon thunderstorms
• Heavy rain on some days

• Busy indoor attractions during the hottest hours

Summer is still a popular time for beach trips, water activities, night markets, festivals, and cooler mountain destinations.

☀️ Travel Tip: Bring sunscreen, sunglasses, a portable fan, water, and an umbrella. Try to avoid long outdoor walks around midday.

Taiwan Typhoon Season

Typhoons are an important weather factor when planning a Taiwan trip during summer and early autumn.

Taiwan's Central Weather Administration considers July the start of the main typhoon season, although tropical systems can affect Taiwan later in the year as well. Historically, several typhoons can approach the area during the second half of the year.

A typhoon does not affect every Taiwan trip during these months, but when one approaches, it may cause:

• Heavy rain
• Strong winds
• Rough sea conditions
• Attraction closures
• Hiking restrictions
• Train or bus changes
• Flight delays or cancellations

⚠️ Important: Check the Central Weather Administration forecast before travelling, especially from July onward. Avoid beaches, mountains, rivers, and coastal areas when official weather warnings are issued.

Autumn in Taiwan: September to November

Autumn is one of the best seasons for Taiwan sightseeing.

September can still feel like summer and may still be affected by typhoons. By October and November, temperatures usually become cooler and humidity gradually decreases.

Typical autumn temperatures are around 20°C to 27°C, although September is usually warmer.

What to expect:

• Warm weather in September
• Cooler days from October
• More comfortable walking weather
• Lower humidity later in the season
• Good conditions for hiking
• Possible typhoons earlier in autumn

Best places to visit: Taipei, Taichung, Sun Moon Lake, Alishan, Jiufen, Tainan, and Kaohsiung.

🍂 Travel Tip: October and November are especially convenient for travelers who want to spend a lot of time outdoors without dealing with Taiwan's strongest summer heat.
