Weather in July
Temperature
The warmest period is July, when temperatures fluctuate between an average high of 82°F (27.8°C) and a low of 65.5°F (18.6°C).Heat index
For most parts of July, the heat index is calculated to be a hot 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
