Weather in May
Temperature
As Dehban transitions into May, the average high-temperature is observed to slightly rise from a warm 27.4°C (81.3°F) in April to a hot 31.4°C (88.5°F). A mild drop to an average of 29.7°C (85.5°F) marks the nights during May.Heat index
Throughout May, the heat index is estimated at a torrid 35°C (95°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.

Never be careless. Unprotected skin and eyes can be harmed swiftly. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
