Weather in May
The last month of the spring, May, is a tropical month in Istubari, Egypt, with an average temperature fluctuating between 16.9°C (62.4°F) and 33.6°C (92.5°F).Temperature
With the transition into May, Istubari experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 29.3°C (84.7°F) in April to a tropical 33.6°C (92.5°F). During May, the nighttime temperature presents a clear descent from the daily peaks, falling to an average of 16.9°C (62.4°F).Heat index
During May, the heat index is computed to be a very hot 36°C (96.8°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
