Weather in July

July, the same as June, in San Guillermo, Philippines, is another tropical summer month, with an average temperature ranging between min 22°C (71.6°F) and max 30.8°C (87.4°F).

Temperature

With the onset of July, the average high-temperature stands at a still hot 30.8°C (87.4°F), closely aligned with June's 32.2°C (90°F). In San Guillermo, the July nights cool down to an average low of 22°C (71.6°F).

Heat index

The heat index value for July is calculated to be a blistering 41°C (105.8°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.

In July, the average relative humidity is 82%.
