Heat index

The heat index in May is calculated to be a blisteringly hot 40°C (104°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in May is 75%.

Implement all key precautions. Warding off sun damage is critical. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Even on a cloudy day, a sunscreen with at least a 30 SPF should be applied generously and frequently reapplied, including after a swim or outdoor exercise. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
