Weather in July
Temperature
July is Selwyn's warmest month, registering average high temperatures of 86°F (30°C) and lows of 63.1°F (17.3°C).Heat index
In July, the heat index is appraised at a very hot 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
