Heat index

Throughout November, the heat index is computed to be a scorching 41°C (105.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

October and November, with an average relative humidity of 76%, are the least humid months.

Rainfall

In Vigia, in November, during 18.8 rainfall days, 69mm (2.72") of precipitation is typically accumulated. In Vigia, during the entire year, the rain falls for 315.6 days and collects up to 2313mm (91.06") of precipitation.

UV index

The months with the highest UV index in Vigia are January, June through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.
Note: A daily high UV index of 7 in November leads to these guidelines:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Attention! UV strength is notably upped by the reflection of sand and water.
