Weather in August

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

Temperature

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

Heat index

The average heat index in August is calculated to a very hot 101.8°F (38.8°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature', 'real feel', 'feels like', or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like activity, differences in body mass, height, and shape, clothing, and metabolic differences affect individual temperature impact. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In Dunedin, the average relative humidity is 73%.

Rainfall

August is the month with the most rainfall in Dunedin. Rain falls for 25.3 days and accumulates 5.16" (131mm) of precipitation.

Note: For swimming, other intense water activities, temperature above 86°F (30°C) is arguably unpleasant, as the water cooling effect is missing.

UV index

Months with the highest UV index in Dunedin are May through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from the exposure to the Sun's UV radiation for average individuals.
Note: The average daily UV index of 7 transform into the following instructions:
Take precautions against overexposure. Protection against sun damage is needed. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
