As
November sets in, there's a continuation of the declining trend in rainfall, witnessed since
September. The reduced precipitation levels of 230mm (9.06"), coupled with increased sunshine hours, create a drier atmosphere. Surprisingly, the temperature, both during the day and at night, sees a marginal increase, maintaining the warmth of the tropical climate. November thus is a month characterized by appreciably drier conditions with substantial daylight. The dry conditions and warm temperatures of this month make it ideal for experiencing all that
Yap has to offer, from its beautiful beaches to its rich cultural showcases.
Temperature
November's onset sees an average high-temperature of a still tropical 30.4°C (86.7°F), exhibiting a slight fluctuation from the previous month. An average minimum temperature of 23.8°C (74.8°F) marks the month of November.
Heat index
November's heat index is estimated at a scorching 40°C (104°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
Humidity
In Yap, the average relative humidity in November is 83%.

UV index
In Yap, the average daily maximum UV index in November is 11. A UV Index estimate of 11, and higher, represents an extreme health hazard from exposure to the Sun's UV rays for the average person.
Note: In November, the maximum UV index of 11 suggests this advice:
Carry out all crucial safety measures, unprotected skin may burn instantly. 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. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Even on a cloudy day, sunscreen with a minimum SPF of 30 should be used liberally and reapplied often, especially after a swim or outdoor activity. Caution! Sand and water reflections can notably increase the UV radiation intensity.
