Temperature

May's weather records an average high-temperature of a tropical 86.2°F (30.1°C), showing little deviation from April. Throughout May, an average low-temperature of 69.4°F (20.8°C) is expected.

Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Note: The UV index of 7 in May translates into these instructions:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
