Weather in July
Temperature
Grand Terrace's transition into July is marked by a minor temperature shift, moving from a warm 85.1°F (29.5°C) in June to a hot 91°F (32.8°C). In Grand Terrace, July nights witness a remarkable decline from the day's zenith to an enjoyable 64.9°F (18.3°C).Heat index
July's heat index is calculated to be a tropical 93.2°F (34°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to 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.
