May weather forecast
Abu Dhabi, United Arab Emirates

May is the transitional month in Abu Dhabi, with the desert heat starting to make its presence felt. The increase in temperatures signals the onset of the intense summer and marks a period of declining rainfall days. The wind becomes a little gentler, and the city’s famous clear skies remain as cloud-cover lowers to only 4%. Despite the rising temperatures, life adapts to the hotter climate. May is the month to explore the region’s air-conditioned indoor offerings.

Temperature

The onset of May introduces a subtle rise in the average high-temperature, nudging from a hot 32.3°C (90.1°F) in April to a torrid 36.5°C (97.7°F). In Abu Dhabi, the May nights cool down to an average low of 29.3°C (84.7°F).

Heat index

May's heat index is calculated to be a blisteringly hot 41°C (105.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Data suggests that the heat index is set for environments in shade and with a light wind. 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 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

The least humid month is May, with an average relative humidity of 43%.

Rainfall

In Abu Dhabi, rain does not fall in May through July and September.

Sea temperature

UV index

In May, the average daily maximum UV index is 8. A UV Index of 8 to 10 symbolizes a very high health hazard from unsafe exposure to UV radiation for ordinary individuals.
Note: The maximum daily UV index, 8 in May, converts into the following recommendations:
Immediate precautions are necessary; otherwise, skin and eyes might get damaged quickly. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Warning! The Sun's UV rays intensify with reflections from sand and water.
