Weather in July
Temperature
July and August are the coldest months, with an average high-temperature of 28.9°C (84°F).Heat index
In July, the heat index is appraised at a sweltering 35°C (95°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
