Weather in May
Temperature
Sealy's weather in May shows a minor rise in the average high-temperature, moving slightly up from April's 78.1°F (25.6°C) to a still warm 84.7°F (29.3°C). Throughout the month of May, the average temperature dips to a refreshing 67.5°F (19.7°C) at night.Heat index
May's heat index is computed to be a very hot 95°F (35°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Be aware that heat index ratings are designed for shaded locations and minor 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 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
