November weather forecast
São Tomé, São Tomé and Príncipe

November paints a vivid picture of fluctuating weather patterns in the archipelagic nation. The span of temperature swings between 22°C (71.6°F) when it's cooled down and accelerates to 29°C (84.2°F), providing a harmonious blend of pleasant and warm climates. With the onset of higher temperatures, November brings back the memories of early-year weather, setting a stage for the year-end with a blooming landscape in the tropics.

Temperature

São Tomé ushers in November with an average high-temperature of a still warm 29°C (84.2°F), showing a close resemblance to the previous month. In São Tomé, November's nights observe an average temperature dip to an agreeable 22°C (71.6°F).

Heat index

The heat index value during November is calculated to be a torrid 36°C (96.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

The months with the highest humidity are January, November and December, with an average relative humidity of 85%.

Rainfall

In November, the rain falls for 11 days. Throughout November, 99mm (3.9") of precipitation is accumulated. In São Tomé, during the entire year, the rain falls for 94 days and collects up to 885mm (34.84") of precipitation.

UV index

January through May, August through December, with an average maximum UV index of 12, are months with the highest UV index. A UV Index reading of 11, and higher, represents an excessive health risk from exposure to the Sun's UV rays for average individuals.
Note: The daily high UV index of 12 during November translates into the following recommendations:
Put into action all crucial precautions. Defense against sun damage is a must. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Despite the overcast weather, sunscreen with SPF of at least 30 should be applied liberally and reapplied often, particularly after swimming or an outdoor workout. Notice! The reflection of water and sand increases the UV radiation significantly.
