Is Taichung too hot in summer?

7 months (April, May, June, July, August, September, October) trip the heat deal-breaker in our scoring: apparent temperature crosses the comfort cap, so even with clear skies and low rain the score is held down. Plan around it if heat tolerance is low.

When are crowds lowest in Taichung?

Search-interest seasonality (Google Trends 2021-2025) is lowest in May and peaks in November. Interest tracks both in-trip visitors and lead-time planners, so treat it as a "destination is on people's minds" signal rather than literal arrivals.

Which months in Taichung have good weather but fewer tourists?

January (climate 9/10, crowd index 1) and February (climate 9/10, crowd index 7) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.

What is the UV index in Taichung in August?

How high can UV get in Taichung on the sunniest days?

Most days look like the monthly average, but on the sunniest ~1 in 10 days UV climbs higher than the mean suggests. August is the worst case: typical days average UV 9 (very high), but the top 10% of days reach UV 11 (extreme) — and even higher. Months where the sunniest days routinely exceed the typical reading: January, February, March, April, May, June, July, August, September, October, November, December. Plan sun protection for the worst case, not the average.

Is air quality in Taichung bad for travelers?

PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 12 months: January, February, March, April, May, June, July, August, September, October, November, December. The worst month is April with a typical-day mean of 38 µg/m³ (hazardous); on the worst 10% of days PM2.5 reaches 53 µg/m³ (hazardous) and higher. People with asthma, heart conditions, or sensitive children may want to avoid these months or limit outdoor activity. Source: CAMS via Open-Meteo.
