Weather in July

July, like June, is another tropical summer month in Dunedin, Florida, with an average temperature fluctuating between 87.4°F (30.8°C) and 79.7°F (26.5°C).

Temperature

The average high-temperature during July is a still tropical 87.4°F (30.8°C), almost matching the conditions of the preceding month. Dunedin sustains an average of approximately a moderately hot 79.7°F (26.5°C) during July nights, with little variation from daytime highs.

Heat index

The heat index value during July is computed to be a very hot 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Humidity

In Dunedin, the average relative humidity in July is 74%.

Rainfall

In Dunedin, during July, the rain falls for 25.6 days and regularly aggregates up to 4.92" (125mm) of precipitation. In Dunedin, during the entire year, the rain falls for 168.5 days and collects up to 27.4" (696mm) of precipitation.

Ocean temperature

In July, the average ocean temperature is 85.6°F (29.8°C).
Note: Swimming, diving, and other water endeavors at temperatures between 77°F (25°C) and 84.2°F (29°C) are considered enjoyable and satisfying for extended periods without discomfort.

Daylight

In Dunedin, the average length of the day in July is 13h and 43min.
On the first day of July, sunrise is at 6:38 am and sunset at 8:31 pm. On the last day of the month, sunrise is at 6:53 am and sunset at 8:21 pm EDT.

Sunshine

The average sunshine in July is 11h.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the average person.
Note: The daily high UV index of 7 during July translates into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key. Alert! Sand and water increase UV exposure due to their reflective properties.
