Weather in May
Temperature
May's onset brings a subtle temperature rise, moving from a moderately hot 73.9°F (23.3°C) in April to a still warm 82.6°F (28.1°C). May generally records an average low-temperature of 61.5°F (16.4°C).Heat index
The heat index value for May is calculated to be a hot 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
