Weather in July
Temperature
The month of July sees the highest average temperatures, reaching 82.4°F (28°C) at the peak and 63.5°F (17.5°C) at the low.Heat index
July's mean heat index is calculated to be a hot 87.8°F (31°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
