Weather in August

August, the last month of the summer in Rock Harbor, is another warm month, with an average temperature varying between 85.5°F (29.7°C) and 82.9°F (28.3°C).

Temperature

August tends to be the warmest month, with temperatures averaging a daily high of 85.5°F (29.7°C) and a low of 82.9°F (28.3°C).

Heat index

The heat index value during August is evaluated at a very hot 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
