July weather forecast
Mariana, Philippines

July, like June, is another tropical summer month in Mariana, Philippines, with an average temperature fluctuating between 25.3°C (77.5°F) and 30.7°C (87.3°F).

Temperature

July welcomes an average high-temperature of a still hot 30.7°C (87.3°F), not much different from the preceding month. Mariana observes an average low-temperature of 25.3°C (77.5°F) during July nights.

Heat index

Throughout July, the heat index is evaluated at a scorching 40°C (104°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
