Weather in May
Temperature
The beginning of May marks a minor shift in the average high-temperature, moving from April's warm 75.7°F (24.3°C) to a still moderately hot 83.7°F (28.7°C). An average low-temperature of 62.2°F (16.8°C) is noted during the month of May.Heat index
During May, the heat index is calculated to be a tropical 91.4°F (33°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
