Weather in July
Temperature
July introduces a minor temperature shift, with average high-temperatures adjusting from June's warm 84°F (28.9°C) to a hot 90°F (32.2°C). Upland records a pronounced decline from the day's peak to an average nighttime low-temperature of 64.8°F (18.2°C) throughout July.Heat index
The heat index value for July is computed to be a tropical 93.2°F (34°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
