May weather forecast
Cucui, Brazil

The last month of the spring, May, is also a moderately hot month in Cucui, Brazil, with an average temperature varying between 29.3°C (84.7°F) and 21.9°C (71.4°F).

Temperature

The lowest temperatures are recorded in May, with averages reaching a high of 29.3°C (84.7°F) and a low of 21.9°C (71.4°F).

Heat index

The average heat index in May is computed to be a very hot 39°C (102.2°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

May is the most humid month, with an average relative humidity of 92%.

Rainfall

In Cucui, in May, during 29.3 rainfall days, 275mm (10.83") of precipitation is typically accumulated. In Cucui, during the entire year, the rain falls for 338.5 days and collects up to 2316mm (91.18") of precipitation.

UV index

The months with the lowest UV index are January through June, August, October and November, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: In May, the maximum UV index of 6 suggests this advice:
Take precautions against overexposure. Protection against sun damage is needed. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
