Weather in July
Temperature
The month of July sees the highest average temperatures, reaching 86.5°F (30.3°C) at the peak and 69.4°F (20.8°C) at the low.Heat index
The heat index value during July is calculated to be a very hot 96.8°F (36°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
