Weather in August
Temperature
In Altoona, August is the warmest month, with temperatures averaging a high of 90.9°F (32.7°C) and a low of 75.7°F (24.3°C).Heat index
The average heat index in August is computed to be a life-threatening hot 114.8°F (46°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.It is worth noting that heat index values are gauged for conditions in the shade and light 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 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
