Weather in July
Temperature
Pierre's warmest temperatures are experienced in July, with average high temperatures of 88.7°F (31.5°C) and lows of 67.5°F (19.7°C).Heat index
In July, the heat index is computed to be a tropical 93.2°F (34°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
