Heat index

During December, the heat index is calculated to be a blistering 40°C (104°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

In Paciran, the average relative humidity in December is 78%.

Note: The UV index of 7 during December translates into the following guidance:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
