Weather in July
Temperature
July, with its average high-temperature of 82°F (27.8°C) and an average low-temperature of 65.3°F (18.5°C), holds the record as the warmest month.Heat index
For most parts of July, the heat index is estimated at a tropical 89.6°F (32°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Consider that heat index readings are for situations in the shade and light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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.
