08Editor's notes
What the numbers don't tell you
August is hot, wet and humid, with afternoons around 33 °C and rain on about twenty days, and Mother's Day on 12 August brings light-blue decorations and a public holiday. European summer holidaymakers lift occupancy a little, though rates stay low. Expect heavy rain on most afternoons and occasional flash flooding on the streets, which clears within an hour.
The Grand Sale discounts continue in the malls. The river is high and brown, and the floating markets outside the city run normally. The Erawan Museum and the Bangkok Art and Culture Centre are the indoor afternoons. Air quality is at its best of the year in the rains. For the wettest month and the lowest prices, see September.
