Weather in May

May, the last month of the spring in Chahestan, is a torrid month, with an average temperature varying between 29.2°C (84.6°F) and 36°C (96.8°F).

Temperature

May signals a minor shift in the average high-temperature, moving from April's hot 31.1°C (88°F) to a sweltering 36°C (96.8°F). In Chahestan, the average nighttime temperature during May is a warm 29.2°C (84.6°F).

Heat index

The heat index value during May is calculated to be a blisteringly hot 41°C (105.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

With an average relative humidity of 45%, May is the least humid month.

UV index

The months with the highest UV index are May and August, with an average maximum UV index of 9. A UV Index reading of 8 to 10 represents a very high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: The UV index of 9 during May leads to these advisories:
Without adequate protection, skin and eyes might suffer damage. Ensure precautions are in place. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key. Even on overcast days, apply and frequently reapply a sunscreen with SPF 30 or more, specifically after a swim or outdoor workout.
