Wet Bulb Globe Temperature (WBGT) Observations
Description
National Environment Agency real-time API of Wet Bulb Globe Temperature (WBGT) observations for Singapore heat-stress assessment, with coverage from February 2025. WBGT averages the past 15 minutes and updates every 15 minutes, combining temperature, humidity, wind, and solar radiation into low, moderate, or high stress bands. Schools, sports organisers, and workplace-safety teams use the feed alongside NEA heat advisories; gaps may occur from instrument issues.
Official description
Real-time API for weather services providing up-to-date WBGT data for heat stress assessment.The heat stress levels are based on Wet-Bulb Globe Temperature (WBGT). WBGT is a composite measure that takes into account air temperature, humidity, wind and solar radiation, and it is different from air temperature. The reported WBGT is an average value calculated over the past 15 minutes and is updated at 15-minute intervals. There are three heat stress levels – low, moderate and high. For more details, please refer to the [heat stress advisory news release](https://www.nea.gov.sg/media/news/news/index/new-heat-stress-advisory-launched-to-guide-public-on-minimising-risk-of-heat-related-illnesses) by MSE and NEA. These data are collected from automated weather instruments, and is automatically published as soon as it is generated. There could be instances when there are gaps in the data due to technical problems. The data is subject to correction subsequently if necessary.
