Weather in July
Temperature
July, noted for its average high-temperature of 85.6°F (29.8°C) and an average low-temperature of 68°F (20°C), is considered the warmest month.Heat index
The heat index for July is calculated to be a torrid 98.6°F (37°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
