Weather in May

May, the last month of the autumn in Ciaul, is another tropical month, with an average temperature ranging between min 24.8°C (76.6°F) and max 31.1°C (88°F).

Temperature

The shift from April to May is characterized by an average high-temperature of a still tropical 31.1°C (88°F), not significantly different from the 30.8°C (87.4°F) of April. Throughout the month of May, Ciaul witnesses an average temperature of 24.8°C (76.6°F).

Heat index

The heat index value during May is calculated to be a blisteringly hot 41°C (105.8°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

In May, the average relative humidity is 78%.

Rainfall

In Ciaul, in May, during 26.5 rainfall days, 118mm (4.65") of precipitation is typically accumulated. Throughout the year, in Ciaul, there are 291.3 rainfall days, and 1460mm (57.48") of precipitation is accumulated.

UV index

The months with the highest UV index are February through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.
Note: The daily maximum UV index of 7 in May interprets into the following advice:
Fend off overexposure. Sun protection is vital. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
