Temperature

The start of May sees the average high-temperature at a tropical 86.4°F (30.2°C), showing little difference from April's 82.6°F (28.1°C). The average low-temperature of 68.5°F (20.3°C) is witnessed during May.

Heat index

The average heat index in May is evaluated at a fiery hot 96.8°F (36°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
