Weather in May
Temperature
A slight uplift in the average high-temperature marks May, adjusting from April's 75.7°F (24.3°C) to a still warm 83.7°F (28.7°C). Throughout May, an average low-temperature of 62.2°F (16.8°C) is expected.Heat index
May's average heat index is computed to be a tropical 91.4°F (33°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
