Weather in July
Temperature
With an average high-temperature of 81°F (27.2°C) and an average low-temperature of 64.2°F (17.9°C), July is the warmest month.Heat index
July's mean heat index is estimated at a tropical 86°F (30°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
