Weather in July
Temperature
Willimantic experiences its highest temperatures in July, with an average peak of 81.9°F (27.7°C) and a low of 63°F (17.2°C).Heat index
In July, the average heat index is computed to be a hot 87.8°F (31°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
