Weather in May
Temperature
The arrival of May introduces a minor uplift in high-temperatures, adjusting from a warm 76.5°F (24.7°C) in April to a still moderately hot 83.3°F (28.5°C). May nights are marked by an average temperature drop to an agreeable 71.1°F (21.7°C).Heat index
During May, the heat index is calculated to be a tropical 89.6°F (32°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees.
