Weather in May
Temperature
The onset of May brings with it an average high-temperature of a still moderately hot 83.7°F (28.7°C), showing a negligible variation from the month before. In the month of May, the average temperature dips to a pleasant 73°F (22.8°C) during the night.Heat index
Throughout May, the heat index is estimated at a tropical 89.6°F (32°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
