Weather in May
Temperature
A gentle upsurge in temperatures occurs as April gives way to May, with average highs shifting from 78.4°F (25.8°C) to a still moderately hot 85.3°F (29.6°C). Nighttime temperature experiences an average drop to a comfortable 66.4°F (19.1°C) in May.Heat index
During May, the heat index is appraised at a very hot 96.8°F (36°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
