Subic, Philippines

The last month of the summer, August, is another warm month in Subic, Philippines, with an average temperature fluctuating between 25.6°C (78.1°F) and 28.9°C (84°F).

Temperature

The ushering in of August brings an average high-temperature of a still warm 28.9°C (84°F), closely mirroring the 29.3°C (84.7°F) of July. Subic notes a consistent average low-temperature of 25.6°C (78.1°F) during August nights.

Heat index

The heat index value for August is computed to be a sweltering 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Take heed! Reflections of sand and water make the Sun's UV rays stronger.
