Weather in May
Temperature
Gastão commences May with an average high-temperature of a still moderately hot 27.8°C (82°F), maintaining a close resemblance to the previous month. May nights observe an average temperature dip to a refreshing 17.8°C (64°F).Heat index
The average heat index in May is evaluated at a hot 31°C (87.8°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.

A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: During May, 6 as the daily maximum UV index converts into the following advice:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. 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.
