Weather in September
Temperature
September's arrival registers an average high-temperature of a still hot 31.2°C (88.2°F), closely aligning with the temperature of the previous month. Kasunyatan experiences an average nighttime temperature of 24.9°C (76.8°F) in the month of September.Heat index
The average heat index in September is appraised at a fiery hot 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.Note: The daily high UV index of 7 in September translates into this advice:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
