Weather in July
Temperature
Dana's July weather, marked by an average high temperature of 81°F (27.2°C) and an average low temperature of 64.6°F (18.1°C), is the warmest in the year.Heat index
For most parts of July, the heat index is computed to be a tropical 87.8°F (31°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
