Weather in May
Temperature
May's arrival sees a mild rise in the average high-temperature, transitioning from April's warm 77.5°F (25.3°C) to a still moderately hot 84.4°F (29.1°C). May is characterized by a distinct thermal shift, with nighttime lows averaging at a comfortable 62.4°F (16.9°C).Heat index
The heat index value during May is appraised at a hot 93.2°F (34°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 particularly relevant to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
