July weather forecast
Arugam Bay, Sri Lanka

July carries forward the momentum of the favorable weather from the preceding months in Arugam Bay. This month's weather shows consistency, especially in terms of sea temperature, daily highs, and lows, reflecting on the stability of the summer. One distinguishing feature of July is the significant decrease in the relative humidity, meaning lesser moisture content in the air. Sunlight dominates the weather pattern for a major part of the day, paving the way for fun at the beach and other outdoor activities. As we approach the end of July, the weather remains comparatively constant, ensuring its suitability for tourists.

Temperature

Arugam Bay notes an average high-temperature of a still tropical 32.6°C (90.7°F) in July, displaying minor variation from June. The nighttime temperature dips to a warm 26.1°C (79°F) on average during July.

Heat index

During July, the heat index is computed to be a scorching 41°C (105.8°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. 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 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity 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 primarily vital for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

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

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
