Chiang Mai in April The hottest month of the year. Songkran starts on the 13th and the whole city becomes a water-fight arena. Bring a waterproof pouch for your phone. Smoke clears as rain begins in late April or early May.
April brought serious heat to Chiang Mai, 37°C on a typical afternoon and 23°C overnight. Early mornings were the best time to be outside. The temperature swung about 13°C within a single day, so midday and evening called for different clothes. Showers came now and then, about 5 rain days in all, and most of the month stayed dry. April was bone dry in 4 of 20 years, yet 2021 brought 11 rain days.
With 29 days above 30°C on average, most of the month felt like high summer. April 2016 averaged 40.0°C by day, 3.5°C above the 20-year mean.

Chiang Mai through the year What to pack Highs of 37°C are serious heat: cover shoulders and the back of the neck, wear a hat, and save sightseeing for the early morning. With a 13°C swing between day and night, dress in layers you can peel off at two in the afternoon and put back on at dusk.
With 5 rain days, a pocket umbrella was insurance rather than a daily tool.
