Weather in May
Temperature
As May arrives, a slight rise in the average high-temperature is observed, moving from 73.9°F (23.3°C) in April to a still moderately hot 81.5°F (27.5°C). May nights cool down to an average low-temperature of 61.2°F (16.2°C).Heat index
May's heat index is calculated to be a tropical 86°F (30°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
