Weather in August

August, the last month of the summer in Altair, is also a hot month, with an average temperature ranging between max 94.6°F (34.8°C) and min 75.4°F (24.1°C).

Temperature

August stands out as Altair's warmest month, with an average high-temperature of 94.6°F (34.8°C) and a low-temperature of 75.4°F (24.1°C).

Heat index

The heat index in August is estimated at a burning hot 122°F (50°C). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
