The weather in July experiences a gradual transition from the preceding month of June. July continues to bear the heat of the summers but with reduced daylight hours. Slightly reduced frequency of rainfall coupled with lesser temperature changes from the previous month constitute the weather scenario for the month. Although still quite humid, the decrease in the rainfall and daylight hours indicate the gradual retreat of the wet season. With a balance between the weather extremes, July offers a certain charm to the city's climate.

Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
