Weather in May
Temperature
The onset of May introduces a subtle rise in the average high-temperature, nudging from a warm 77.9°F (25.5°C) in April to a still moderately hot 85.3°F (29.6°C). May nights bring a pronounced temperature shift, with averages hovering around a comfortable 63.3°F (17.4°C).Heat index
Throughout May, the heat index is calculated to be a tropical 93.2°F (34°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
