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 starts July with an average high-temperature of a still tropical 32.6°C (90.7°F), hinting at a minimal fluctuation from June. Arugam Bay records an average nighttime low of 26.1°C (79°F) in July.

Heat index

The heat index value for July is evaluated at a scorching 41°C (105.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: A daily maximum UV index of 7 in July translates into the following instructions:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. 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. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
