August weather forecast
Yap, Micronesia

As the calendar flips to August, there's a maintenance of wet conditions, indicated by a high precipitation level of 386mm (15.2"), the highest among all months. The relative humidity at this time of the year stays high, dense cloud cover is prevalent, and wet conditions persist. Despite the wet conditions, the daytime and night-time temperatures remain consistent with those of previous months. Although weather conditions may seem challenging, this month offers a unique opportunity to experience Yap's ecology during peak monsoon. August provides a chance to interact closely with the natural environment of the region, especially its diverse aquatic life.

Temperature

A minimal variation is noted in Yap's average high-temperature at the onset of August, reaching a still hot 30.8°C (87.4°F) from July's 30.6°C (87.1°F). Throughout August nights, Yap experiences a consistent temperature average of 23.4°C (74.1°F).

Heat index

In August, the average heat index is estimated at an extremely hot 42°C (107.6°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. 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 July through October, with an average relative humidity of 84%.

Rainfall

August is the month with the most rainfall. Rain falls for 20.9 days and accumulates 386mm (15.2") of precipitation.

Sea temperature

The months with the warmest seawater are May through December, with an average sea temperature of 29°C (84.2°F).
Note: Surface water temperatures ranging from 25°C (77°F) to 29°C (84.2°F) are seen as ideal and highly pleasant for extended enjoyment in all water activities.

Daylight

In August, the average length of the day in Yap is 12h and 26min.
On the first day of the month, sunrise is at 06:37 and sunset at 19:09. On the last day of August, sunrise is at 06:38 and sunset at 18:57 +10.

Sunshine

In Yap, the average sunshine in August is 5.7h.

UV index

The months with the highest UV index are February through October, with an average maximum UV index of 12. A UV Index of 11, and more, symbolizes an extreme threat to health from exposure to the Sun's UV radiation for ordinary individuals.
Note: A maximum daily UV index of 12 during August morphs into the following directions:
Execute every important safeguard, as unprotected skin and eyes could burn within moments. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Applying and reapplying liberally a broad-spectrum sunscreen of SPF 30+ every two hours, and straight after a swim or outdoor activity is recommended. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
