Weather in September
Temperature
September sees a slight reduction in average high-temperature, with a shift from a sweltering 97.9°F (36.6°C) in August to a hot 92.5°F (33.6°C). La Villa reports a consistent average low-temperature of 77.4°F (25.2°C) throughout September nights.Heat index
The heat index value during September is evaluated at a scorching 111.2°F (44°C). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Deflect overexposure. Sun protection is a necessity. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
