Temperature

The advent of May brings an average high-temperature of a still tropical 30°C (86°F), almost identical to the preceding month. In the month of May, an average of 20.5°C (68.9°F) marks the low-temperature.

Heat index

The heat index for May is computed to be a very hot 36°C (96.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
