Weather in September
Temperature
The transition into September is marked with an average high-temperature of a still tropical 88°F (31.1°C), showing an insignificant shift from August's 90.9°F (32.7°C). Laguna Vista, during September nights, experiences a subtle shift to a low average of 79.5°F (26.4°C) from the day's heat.Heat index
The heat index value during September is estimated at a very hot 100.4°F (38°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Prevent overexposure. Protection from the sun's harmful effects is needed. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
