February weather forecast
Yap, Micronesia

Transitioning into February, it becomes noticeable that the weather conditions tend to persist much like in January, albeit with subtle changes. February sees slightly less precipitation, with rainfall dropping to 152mm (5.98") spread across fewer days. This reduction in rainfall, coupled with an increment in sunshine hours, signifies drier conditions in comparison to January. The quiet and serene atmosphere created by this relative dryness reflects the charm of Yap during this month. As the month progresses, the weather becomes more conducive for outdoor activities, marking February as the perfect month to experience Yap's rich cultural heritage.

Temperature

The arrival of February coincides with an average high-temperature of a still tropical 30.2°C (86.4°F), indicating a minimal shift from January's 30.1°C (86.2°F). The average temperature drops to a moderately hot 23.5°C (74.3°F) during the night in the month of February.

Heat index

During February, the heat index is estimated at a fiery hot 39°C (102.2°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Note that heat index values are valued for light wind and location in the shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

In February, the average relative humidity is 81%.

Rainfall

In Yap, in February, during 13.4 rainfall days, 152mm (5.98") of precipitation is typically accumulated. Throughout the year, there are 211.6 rainfall days, and 3050mm (120.08") of precipitation is accumulated.

Sea temperature

The months with the coldest seawater are January through April, with an average sea temperature of 28°C (82.4°F).
Note: In water activities such as swimming and diving, temperatures from 25°C (77°F) to 29°C (84.2°F) are deemed highly pleasurable for extended periods without any unease.

Daylight

In February, the average length of the day is 11h and 50min.
On the first day of February, sunrise is at 07:09 and sunset at 18:52. On the last day of the month, sunrise is at 07:01 and sunset at 18:58 +10.

Sunshine

The average sunshine in February is 7.6h.

UV index

February through October, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an excessive health risk from unsafe exposure to UV radiation for the average person.
Note: In February, the maximum UV index of 12 translates into these guidelines:
Take all required precautions, as unprotected skin and eyes can burn in minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun. 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. Be mindful! Sand and water reflections can up the Sun's UV exposure.
