Heat index
Throughout May, the heat index is calculated to be a blazing hot 45°C (113°F).
Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Practice every precaution of necessity, unprotected skin and eyes might burn in minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Sunscreen of at least SPF 30 should be applied generously and reapplied often on overcast days, especially post swim or outdoor exercise. Notice! The Sun's UV exposure elevates with sand and water reflections.
