May weather forecast
Crater, Yemen

May in Crater, Yemen witnesses the highest leap in average high temperature, from 29.8°C (85.6°F) to 31.9°C (89.4°F), creating a much warmer atmosphere than the preceding month. Despite the moderate increase in cloud cover, the average daily sunshine remains constant. However, a significant change occurs in the rainfall pattern, with an increase in rainfall volume. The movement into June marks very minute changes in weather parameters. Thus, May indicates the onset of summer with its warm temperatures but still retains the charm of spring with its reasonable rainfall and ample sunshine.

Temperature

At the start of May, Crater's average high-temperature reaches a hot 31.9°C (89.4°F), subtly different from the preceding month. An average nighttime temperature of 29.2°C (84.6°F) marks May.

Heat index

May's heat index is evaluated at a scorching 40°C (104°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

The average relative humidity in May is 71%.

Rainfall

The months with the most rainfall are May and August, with an average 9mm (0.35") of precipitation.

UV index

The months with the highest UV index are May through September, with an average maximum UV index of 8. A UV Index value of 8 to 10 symbolizes a very high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: The maximum UV index, 8 during May, leads to the following recommendations:
It is essential to prioritize protection. Unprotected skin and eyes can suffer rapid harm. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
