July sees the mercury remain consistent, with high temperatures hovering around a comfortable 30.6°C (87.1°F) margin. The hallmark of July's weather in
Yap is the peak in precipitation levels, logging rainfall figures at an astonishing 369mm (14.53"). This level of rainfall converges with the highest relative humidity levels to underscore the tropical wet climate associated with Yap in July. Lush vegetation flourishes due to the abundant rainfall and high humidity, casting a vibrant green hue across the island. Such climatic conditions favor indoor activities and create a distinct charm associated with visiting Yap during the peak wet season.
Temperature
In July, Yap's weather conditions record an average high-temperature of a still tropical 30.6°C (87.1°F), demonstrating little divergence from the preceding month. An average temperature of 23.4°C (74.1°F) is recorded in Yap during the nights in July.
Heat index
The heat index for July is appraised at a scorching 41°C (105.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Take all necessary precautions, as unprotected skin can burn in minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Broad-spectrum sunscreen with an SPF of 30 or above should be applied generously and reapplied every two hours and right after any outdoor activity or swim. Caution! The Sun's UV intensity grows with reflections off sand and water.
