Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 81.3°F (27.4°C) and a low of 64.8°F (18.2°C).Heat index
The average heat index in July is estimated at a tropical 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
