Weather in May
Temperature
With the onset of May, the average high-temperature subtly transitions from 78.6°F (25.9°C) in April to a still warm 85.5°F (29.7°C). Throughout May, the temperature falls to an average low of 65.5°F (18.6°C).Heat index
In May, the average heat index is calculated to be a very hot 96.8°F (36°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
