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

As August unfolds, the average high-temperature reaches a still hot 30.8°C (87.4°F), hinting at a slight fluctuation from the previous month. In August, the recorded average low-temperature is a warm 23.4°C (74.1°F).

Heat index

The average heat index in August is appraised at a scorching 42°C (107.6°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Implement all key precautions. Warding off sun damage is critical. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Apply and frequently reapply a minimum SPF 30 sunscreen even on cloudy days, especially after swimming or an outdoor workout. Heads up! UV intensity is amplified by reflections from water and sand.
