July weather forecast
Sydney, FL

July, like June, is a hot summer month in Sydney, Florida, with an average temperature varying between 89.6°F (32°C) and 76.1°F (24.5°C).

Temperature

Sydney records an average high-temperature of a still tropical 89.6°F (32°C) as July arrives, nearly mirroring the previous month's climate. In July, Sydney experiences a temperature dip to an average of 76.1°F (24.5°C) at night.

Heat index

Throughout July, the heat index is estimated at a blisteringly hot 109.4°F (43°C). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
The standards for the heat index are set for locations in shade and under light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In Sydney, the average relative humidity in July is 77%.

Rainfall

UV index

Note: A daily maximum UV index of 7 in July translates into the following instructions:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
