The ambient temperature of the air, measured in the shade. It reflects the baseline thermal condition of the environment.
The actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.
The total radiant energy from the sun that reaches the Earth’s surface including both direct sunlight and diffuse sky radiation.
The rate of air movement measured at human height, influencing the body’s ability to dissipate heat through convection and evaporation.

The WBGT is a scientifically validated index used to estimate heat stress in humans, taking into account multiple environmental factors such as air temperature, humidity, wind speed, and solar radiation. Unlike simple temperature readings, WBGT reflects the combined effect of radiant heat and humidity on the body, offering a much more realistic measure of the potential for heat-related illnesses like heat exhaustion or heat stroke. WBGT is widely used by occupational safety agencies and organizations (e.g., ILO, ISO, NIOSH, ACGIH, and military guidelines) to define exposure limits, rest-work cycles, and hydration needs for workers in hot environments.
EVERADE employs a unique modeling approach that integrates high-resolution meteorological data with advanced algorithms. We combine real-time weather inputs from both satellite and ground-based sources to calculate WBGT using location-specific models aligned with established standards and validated scientific literature. Our results are continuously verified against professional-grade instruments to ensure accuracy and reliability at every site. This enables EVERADE to deliver historical, real-time, and forecasted WBGT estimates, even in areas without on-site sensors, making it ideal for large operations, urban environments, and remote locations.
EVERADE stands out for its scientific accuracy, reliability, and flexibility. Our platform is built on validated heat stress models used in occupational and environmental physiology research, ensuring compliance with international standards and organizations. Beyond monitoring, EVERADE provides predictive analytics, smart alerts, and automated risk classification to help organizations proactively manage worker safety before heat incidents occur. We also offer audit-ready logs, customizable dashboards, and integration options with existing safety systems, apps, and APIs—making it the most adaptable and future-proof WBGT solution available.
Unlike simple metrics like the “Heat Index” or “Apparent Temperature,” WBGT incorporates the effects of solar radiation, humidity, wind, and air temperature all together. For example, the Heat Index assumes shaded conditions with low air movement, which can significantly underestimate real-world heat exposure especially for outdoor workers or athletes in direct sunlight. WBGT, on the other hand, includes the globe temperature (which measures radiant heat from the sun and surrounding surfaces) and the natural wet-bulb temperature (which captures the cooling effect of evaporation). As a result, WBGT provides a far more accurate representation of total thermal load on the human body, making it the standard used by occupational health professionals, the military, and sports governing bodies worldwide.
