Weather in August

August, the last month of the summer in Dunedin, is also a hot month, with an average temperature ranging between min 80.4°F (26.9°C) and max 88°F (31.1°C).

Temperature

August is the warmest month, with the temperature often reaching an average high of 88°F (31.1°C) and an average low of 80.4°F (26.9°C).

Heat index

August's average heat index is evaluated at a torrid 102.2°F (39°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Reflective properties of sand and water amplify the Sun's UV radiation.
