Weather in July
Temperature
Stafford witnesses the warmest weather in July, with temperatures averaging a high of 88.7°F (31.5°C) and a low of 67.8°F (19.9°C).Heat index
The heat index value during July is evaluated at a blistering 104°F (40°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
