Weather in September
Temperature
The average high-temperature during September registers at a moderately hot 29.6°C (85.3°F), closely corresponding to the preceding month. During September's nights, Marigondon notes a minor temperature decline, reaching an average of 25.6°C (78.1°F).Heat index
For most parts of September, the heat index is calculated to be a very hot 36°C (96.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the average person.Note: The daily high UV index of 7 during September translates into the following recommendations:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. To cut down UV radiation exposure by about half, sport a wide-brim hat.
