Weather in May
Temperature
Alief's May weather indicates a minor increase in high-temperatures, edging from April's 78.6°F (25.9°C) to a still warm 85.5°F (29.7°C). Throughout May, Alief registers a consistent average low-temperature of 68.5°F (20.3°C).Heat index
During May, the heat index is evaluated at a torrid 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
