Weather in August
Temperature
July's transformation into August witnesses an average high-temperature of a still moderately hot 81.7°F (27.6°C), noting a minor change from the preceding month. Gladstone's nights in August cool down to an average low-temperature of 63.5°F (17.5°C).Heat index
For most parts of August, the heat index is computed to be a tropical 87.8°F (31°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
