Pattaya in September

One of the rainiest months. It is easier to cut back on the beach and build days around spa, massage and malls. Showers can catch you in transit, so carry an umbrella.

Pattaya in September ran hot: 31°C by day and 25°C at night. By midday the shade was the best seat in town. About 14 days a month saw rain, enough that a wet-weather plan was worth having. The driest year, 2011, had 10 rain days; the wettest, 2006, had 21.

With 25 days above 30°C on average, most of the month felt like high summer. Wet days did not mess around: about 17 mm each, the kind of rain that drives you into a doorway.
