August holds the record for the highest monthly average temperature, with the high peaking at 29.5°C (85.1°F) and the low at 21.2°C (70.2°F). The sun bathes the city for 13.3 hours on average-with 11.5 hours of shining sunshine. Despite a near absence of rainfall, with just 1mm (0.04") over 0.1 days, there's little cause for concern as humidity isn't oppressive. As temperatures skim 30°C (86°F), beach activities and sea swims become even more popular. Given the hot weather, it is essential to stay hydrated, particularly for those planning outdoor activities.
Temperature
In
Marsa Matruh, the peak average temperatures are observed in August, with a high of 29.5°C (85.1°F) and a low of 21.2°C (70.2°F).
Heat index
The average heat index in August is estimated at a very hot 35°C (95°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Note: The UV index of 11 during August leads to these advisories:
Adopt all important safety measures, unprotected skin may burn rapidly. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Directly after outdoor activities or swimming, a broad-spectrum sunscreen with SPF 30+ should be applied generously and reapplied frequently. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
