Weather in July

If Manchester has a hot season, July holds the best claim to the title as the mercury climbs to 81.7°F (27.6°C). The absence of snow and the eleven rain days on average define the month. With the UV Index reaching its peak, it's a key time for summer dressing and sunscreen. Though it's typically the warmest time of the year, the decline in wind gusts makes it seem even hotter.

Temperature

In Manchester, New Hampshire, July is the month with the highest recorded average temperatures, measuring a high of 81.7°F (27.6°C) and a low of 61°F (16.1°C).

Heat index

The average heat index in July is computed to be a hot 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
