Heat index

The heat index for May is evaluated at a sweltering 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Note: The UV index of 6 during May leads to these advisories:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
