Weather in May
Temperature
May's arrival brings a slight change in high-temperatures, adjusting from a warm 80.1°F (26.7°C) in April to a tropical 86°F (30°C). During the month of May, the nighttime temperature falls to an average of 66.4°F (19.1°C).Heat index
For most parts of May, the heat index is calculated to be a torrid 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
