Temperature

During the warmest month, May, temperatures average a high of 33.1°C (91.6°F) and a low of 25.5°C (77.9°F).

Heat index

During May, the heat index is calculated to be a blistering 44°C (111.2°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Heat index values are typically calculated for conditions of shade and a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Note: In May, a regular UV index of 7 translates into these guidelines:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. 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. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
