Temperature

The arrival of May denotes a barely perceptible change in the average high-temperatures to a tropical 86.4°F (30.2°C) from April's 82°F (27.8°C). Throughout the month of May, the average temperature dips to an agreeable 70.3°F (21.3°C) at night.

Heat index

May's average heat index is calculated to be a sweltering 96.8°F (36°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

The months with the lowest humidity are March through May, with an average relative humidity of 71%.

Note: In May, a daily maximum UV index of 7 leads to the following instructions:
Ward off overexposure. Defence against solar harm is crucial. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
