Weather in May
Temperature
Observing a slight rise in May, the average high-temperature shifts from April's moderately hot 77.7°F (25.4°C) to a still warm 84.7°F (29.3°C). During May nights, Lake Arthur records an average temperature of 68.9°F (20.5°C).Heat index
May's average heat index is calculated to be a tropical 93.2°F (34°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
