Weather in May
Temperature
With the transition into May, Crystal City experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 84.9°F (29.4°C) in April to a hot 90.7°F (32.6°C). The temperature lowers to an average of 70.3°F (21.3°C) during May nights.Heat index
In May, the average heat index is estimated at a very hot 102.2°F (39°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
