Weather in October

October, like September, is another tropical autumn month in San Rafael, Philippines, with an average temperature fluctuating between 25.3°C (77.5°F) and 30.8°C (87.4°F).

Temperature

September's transformation into October witnesses an average high-temperature of a still hot 30.8°C (87.4°F), consistent with the conditions of the preceding month. During October, San Rafael's temperature falls to a steady low-temperature average of 25.3°C (77.5°F).

Heat index

In October, the average heat index is estimated at a blistering 40°C (104°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
The metrics for the heat index are tailored for both shady environments and light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

The months with the lowest UV index in San Rafael are January through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.
Note: A daily high UV index of 7 in October leads to these guidelines:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
