June weather forecast
Phuket, Thailand

In June, Phuket makes it past half the year with wetter conditions being more persistent. While temperatures remain relatively stable, the monsoon season is in full swing with rainfall consistent at 213mm (8.39"). Sunbathing might require careful planning due to fewer sunshine hours. Despite the increase in rainfall days, the sea temperature stays warm, appealing to swimmers and divers. The weather pattern in June largely mirrors that of July.

Temperature

The average high-temperature in Phuket is a still tropical 32.4°C (90.3°F) in June, hardly different from the 32.8°C (91°F) recorded in May. Nighttime temperatures in Phuket consistently average a moderately hot 25.5°C (77.9°F) during June.

Heat index

For June, the heat index is estimated at a life-threatening hot 45°C (113°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

The average relative humidity in June in Phuket is 79%.

Note: In June, a daily maximum UV index of 12 leads to the following instructions:
Enforce every key safety measure. Those with light skin might get burns in a matter of minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Sunscreen with an SPF of 30 or higher should be applied generously and frequently reapplied even on cloudy days, especially after each swim or outdoor workout. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
