Temperature

The warmest period is May, when temperatures fluctuate between an average high of 37.7°C (99.9°F) and a low of 28.4°C (83.1°F).

Heat index

Throughout May, the heat index is appraised at a life-threatening hot 48°C (118.4°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
