Weather in July
Temperature
July is the warmest month, with an average high-temperature of 86.7°F (30.4°C) and an average low-temperature of 69.8°F (21°C).Heat index
July's mean heat index is appraised at a very hot 98.6°F (37°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
