If you want to walk around Bangkok’s Grand Palace, temples and riverside, consider November–February. Rainfall drops sharply from November after the wetter months of September and October, and average temperatures in December and January are around 27°C, more comfortable than April’s heat. Average daytime highs still exceed 32°C, so visit temples in the morning, walk by the river near sunset and leave time in between for meals and indoor breaks.

Plan Grand Palace and temple walks in the morning or around sunset. Set aside midday for meals and rest to avoid long walks in the heat. On rainy days, consider Riding the train between cafés and shopping malls.
Pack light clothing, a hat and umbrella. Rest in shade or indoors between outdoor journeys. Have a plan to wait nearby indoors if a downpour arrives, rather than traveling far through it.
For walking between temples and markets, November–February is a good choice. December and January average around 27°C, with relatively little monthly rain: 11.6 mm and 23.6 mm respectively. Think of this as a way to avoid April’s intense heat and the rainy season’s heavier downpours rather than a cool winter.
Look at average highs and lows too. The average temperature is not a reading at one particular time of day. Prepare separately for midday walks and for mornings or evenings outside.
No. Rainy-day counts are monthly averages, not the hours or duration of rainfall. Read the hourly forecast for your actual travel dates and adjust outdoor plans.
