Temperature

May is the warmest month, with the temperature often reaching an average high of 32.7°C (90.9°F) and an average low of 25.6°C (78.1°F).

Heat index

The heat index in May is estimated at a life-threatening hot 45°C (113°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
