July weather forecast
Kalmunai, Sri Lanka

July continues the summer trend ceasing the downward shift witnessed in June. The weather pattern is near-identical to June, with only minor fluctuations in temperature and rainfall. This relative stability in weather parameters creates a predictable climate, featuring typical characteristics of a tropical summer. The month's predictability allows residents to plan outdoor activities with certainty, providing a window of consistency amidst an otherwise fluctuating climate.

Temperature

Entering July, Kalmunai's average high-temperature reads a still tropical 32.6°C (90.7°F), indicating a close resemblance to the previous month's climate. An average minimum temperature of 26.1°C (79°F) marks the month of July.

Heat index

In July, the average heat index is computed to be a blisteringly hot 41°C (105.8°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Humidity

The months with the lowest humidity are June and July, with an average relative humidity of 68%.

UV index

January through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the ordinary person.
Note: A maximum high UV index of 7 in July translates into the following recommendations:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
