Weather in May
Temperature
The shift from April to May is marked by a slight increase in the average high-temperature, moving from 77.5°F (25.3°C) to a still warm 84.6°F (29.2°C). During the month of May, the temperature falls to an average of 67.5°F (19.7°C).Heat index
May's mean heat index is estimated at a tropical 93.2°F (34°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. 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 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
