Heat index

The heat index value during May is computed to be a hot 34°C (93.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.

Humidity

The average relative humidity in May is 76%.

A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for ordinary individuals.
Note: A maximum high UV index of 7 in May translates into the following recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half. Stay aware! UV radiation is magnified when reflecting off sand and water.
