Weather in May
Temperature
The shift into May records an average high-temperature of a still tropical 93.2°F (34°C), subtly varied from April's 88°F (31.1°C). An average nighttime temperature of 73°F (22.8°C) is observed during May.Heat index
The average heat index in May is appraised at a scorching 107.6°F (42°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

As much as possible, limit direct sun exposure during this period. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
