March weather forecast
Yap, Micronesia

The arrival of March signals a continuation of warm conditions, typical of Yap's tropical setting. In this month, a marginal increase in both the daytime high temperature and night-time low temperature occurs. The decrease in rainfall to 151mm (5.94") and increased daylight hours imply longer, drier periods. March offers ample opportunities for sunbathing and beach activities without the interruption of heavy rainfalls. The mild temperatures of the sea water further enhance the attractiveness of beach-related activities during this month.

Temperature

The beginning of March records an average high-temperature of a still hot 31.1°C (88°F), marking a negligible difference from February's 30.2°C (86.4°F). Throughout March, an average low-temperature of 24°C (75.2°F) is expected.

Heat index

The heat index for March is estimated at a blistering 41°C (105.8°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in March is 80%.

Rainfall

In Yap, during March, the rain falls for 13.7 days and regularly aggregates up to 151mm (5.94") of precipitation. In Yap, during the entire year, the rain falls for 211.6 days and collects up to 3050mm (120.08") of precipitation.

Sea temperature

January through April, with an average sea temperature of 28°C (82.4°F), are months with the coldest seawater.
Note: Engaging in swimming, diving, or other water activities is highly enjoyable in temperatures ranging from 25°C (77°F) to 29°C (84.2°F), without any unpleasant sensations for prolonged durations.

Daylight

The average length of the day in March is 12h and 5min.
On the first day of March, sunrise is at 07:01 and sunset at 18:58. On the last day of the month, sunrise is at 06:45 and sunset at 18:57 +10.

Sunshine

The average sunshine in March is 8.1h.

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 exposure to the Sun's UV radiation for the ordinary person.
Note: In March, the maximum UV index of 12 translates into these guidelines:
Adopt every precaution of necessity, unprotected skin and eyes may suffer burns instantly. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Even on a cloudy day, a sunscreen with at least a 30 SPF should be applied generously and frequently reapplied, including after a swim or outdoor exercise. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
