Temperature

Naranwala's entry into February measures an average high-temperature of a still hot 31.4°C (88.5°F), closely parallel to the preceding month. During February, Naranwala records a consistent average nighttime temperature of 23.3°C (73.9°F).

Heat index

In February, the average heat index is computed to be an extremely hot 40°C (104°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Take precautions against overexposure. Protection against sun damage is needed. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
