May weather forecast
Shibam, Yemen

May typifies the harsher summer weather in Shibam, Yemen, with the mercury soaring to 32.6°C (90.7°F). The weather, when juxtaposed with April, reveals intensified aridity and higher temperatures. Moisture levels, measured as relative humidity, follow a near stasis despite the granular rise in rainfall to 5mm (0.2"). Sunshine duration ascends to its annual zenith of 12.1 hours, complemented by extended daylight hours of 12.9. Wind movements register an almost standstill mode, providing little cooling aid amidst the torrid weather.

Temperature

Shibam registers an average high-temperature of a still tropical 32.6°C (90.7°F) at the commencement of May, closely related to the preceding month. An average minimum temperature of 25.5°C (77.9°F) is recorded during the month of May.

Heat index

The heat index for May is calculated to be a torrid 38°C (100.4°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

In May, the average relative humidity is 58%.

Rainfall

In May, the rain falls for 3.8 days. Throughout May, 5mm (0.2") of precipitation is accumulated. In Shibam, during the entire year, the rain falls for 35.5 days and collects up to 65mm (2.56") of precipitation.

Daylight

In May, the average length of the day is 12h and 52min.
On the first day of the month, sunrise is at 05:20 and sunset at 18:04. On the last day of May, sunrise is at 05:12 and sunset at 18:13 +03.

Sunshine

The average sunshine in May is 12.1h.

UV index

In May, the average daily maximum UV index is 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: In May, the maximum UV index of 7 suggests these recommendations:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
