Weather in May
Temperature
The arrival of May witnesses a small shift in the average high-temperature, moving from a moderately hot 77.7°F (25.4°C) in April to a still warm 84.7°F (29.3°C). An average low-temperature of 68.9°F (20.5°C) is recorded during the nights in May.Heat index
During May, the heat index is computed to be a hot 93.2°F (34°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
