What August actually feels like
August is Bangkok's hot summer in lived terms: continued monsoon. Most days feel cold, dry and often clear, with damper grey stretches arriving in bursts rather than settling in for the whole month Check the full climate tables below for monthly averages and packing cues.
The underestimated variable is clustered wet days. It truncates outdoor evenings and pushes dinner earlier. Build one indoor spare block every day Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Early August often starts near 31°C while the final week trends toward 33°C. That 1° drift is enough to change coat weight mid-trip. Recheck the forecast before packing day seven Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Afternoons reach 32–33°C before an early sunset near the 14-hour daylight limit — plan open-air stops then.
Evenings cool quickly toward 25°C; shift to indoor dining and illuminated streets once the light drops.
