June's weather showcases a tropical phenomenon, where abundant sunshine coexists with recurrent showers, thereby highlighting Yap's unique climatic disposition.
Temperature
Transitioning into June, Yap records an average high-temperature of a still hot 30.7°C (87.3°F), almost identical to
May's 30.9°C (87.6°F). Yap cools down to an average low-temperature of 23.6°C (74.5°F) throughout the month of June.
Heat index
In June, the average heat index is appraised at a scorching 41°C (105.8°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Practice all essential precautions. Protection against sun damage is crucial. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Apply and frequently reapply a broad-spectrum SPF 30+ sunscreen after every two hours, or immediately after a swim or outdoor exercise. Alert! Sand and water increase UV exposure due to their reflective properties.
