Weather in May
Temperature
The introduction of May notes a subtle temperature variation to a still hot 32.1°C (89.8°F) from April's 33.8°C (92.8°F). May's nights observe an average temperature of 22.2°C (72°F).Heat index
May's average heat index is estimated at an extremely hot 43°C (109.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection.
