Kaohsiung in May

The rainy season begins. Rain that was rare through April jumps, and afternoon thunderstorms become frequent. If you packed with the dry season in mind, add an umbrella.

Highs averaged 30°C and lows stayed at 25°C, so the heat hung on long after sunset. The month averaged 19 rain days. Carry an umbrella. Averages hide a lot here: one year saw 5, another 28.

The switch flipped here: 11 rain days the month before, 19 in May. Highs topped 30°C on 18 days of the month on average. Mixing in indoor stops at midday made sense.
