Weather in May
Temperature
May sees a marginal temperature increase, moving from 76.6°F (24.8°C) in April to a still warm 84°F (28.9°C). A steady average of 62.2°F (16.8°C) throughout May underscores a considerable divergence from the daytime high.Heat index
In May, the heat index is estimated at a tropical 91.4°F (33°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
