November weather forecast
Sámara, Costa Rica

Graduating from the peak rainy season, November exhibits a decrease in rainfall to 96mm (3.78") in Sámara, Costa Rica. Weather parameters such as temperature and relative humidity levels display little deviation from the preceding month. Interestingly, sea temperature steadily maintains an inviting warmth as winds observe a slight increase in speed. Despite a slight drop in daylight hours, the UV index of 7 continues unabated throughout this month. Cloud cover continues its dominance in the sky, shielding the city from excessive sunlight exposure.

Temperature

The beginning of November records an average high-temperature of a still warm 29°C (84.2°F), almost echoing the conditions of the previous month. Sámara's temperature drops to an average low of 23.3°C (73.9°F) during the nights of November.

Heat index

The heat index value during November is calculated to be a sweltering 35°C (95°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.
Note: In November, the maximum UV index of 7 suggests this advice:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
