Weather in August

August, the last month of the summer in Alpine, is another hot month, with temperature in the range of an average high of 92.8°F (33.8°C) and an average low of 71.1°F (21.7°C).

Temperature

August's advent denotes a minor fluctuation in the average high-temperature to a still tropical 92.8°F (33.8°C) from July's 93.2°F (34°C). Alpine logs a substantial downturn to an agreeable 71.1°F (21.7°C) during August nights, a considerable shift from daytime highs.

Heat index

The heat index in August is computed to be a burning hot 116.6°F (47°C). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Remember, however, that shade structures may not provide complete protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
