What changes across the day

Based on the available hourly WeatherAPI forecast

Peak heat index

35°C at 12:00 PM

The preview low is 28°C around 8:00 AM.

Feels-like difference

3°C above air temp

Current humidity is 66%, one input that changes evaporative cooling.

Peak UV

8.7 at 12:00 PM

UV and heat are separate hazards; the lowest-heat hour may still need sun protection.

Tomorrow's direction

1°C cooler tomorrow

Today's forecast range is 25°C–31°C.

Where these numbers come from

WeatherAPI supplies the forecast. HeatGuard calculates heat-index risk and models WBGT from forecast temperature, humidity and a daytime solar allowance. Modeled WBGT is not an on-site globe-thermometer reading.

Local planning context

Planning for heat in Bangkok, Thailand

Bangkok's persistent humidity, urban heat and strong daytime sun can produce demanding conditions for outdoor work. Thailand's occupational guidance uses WBGT, workload and exposure time when evaluating workplace heat.

Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
