The monsoon sets in completely by
July, bringing high precipitation and high humidity. The weather is significantly cooler than in
June. The dramatic spurt in rainfall, to a startling 265mm (10.43"), is an exceptional characteristic of this month. The substantial downpours, coupled with the decline in the scorching heat, bathe
Allahabad in balmy weather. All these factors bring many days of cloud cover, which in turn reduces the hours of sunshine.
Temperature
The onset of July in Allahabad brings a small change in high-temperatures, falling from a sweltering 39.6°C (103.3°F) in June to a hot 34.2°C (93.6°F). Throughout July, an average low-temperature of 26.5°C (79.7°F) is expected.
Heat index
In July, the average heat index is calculated to be a life-threatening hot 51°C (123.8°F).
On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
