Weather in May
Temperature
With the onset of May, Weir observes a minor temperature ascent, with the average high-temperature adjusting from April's moderately hot 73.9°F (23.3°C) to a still warm 82°F (27.8°C). Weir's nighttime temperature in May drops to an average of 62.2°F (16.8°C).Heat index
During May, the heat index is calculated to be a hot 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.The standards for the heat index are set for locations in shade and under light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
