Weather in May
Temperature
May introduces a marginal temperature uplift, with average high-temperatures adjusting from April's warm 74.7°F (23.7°C) to a still moderately hot 81.7°F (27.6°C). Thornton records an average temperature drop to a refreshing 64°F (17.8°C) in May.Heat index
The heat index value for May is estimated at a hot 87.8°F (31°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
