Weather in July
Temperature
The transition into July shows a subtle variation to a still moderately hot 29.5°C (85.1°F) from June's 28.8°C (83.8°F) in the average high-temperature. During July, Saint-Bernard records an average temperature of 24.3°C (75.7°F) at night.Heat index
The heat index in July is estimated at a sweltering 36°C (96.8°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
