June weather forecast
Ko Lanta, Thailand

June sees continuity in the wet season, with substantial rainfall and high humidity characterising the weather in Ko Lanta. Although the temperature decreases slightly from May, the heavy cloud cover and abundant rain make this a less desirable time for outdoor activities. The excessive rain does, however, create an ideal ecosystem for the local flora and fauna to flourish. With the coming of July, the rainfall intensifies even further, but the temperature and relative humidity remain stable.

Temperature

The onset of June in Ko Lanta brings with it an average high-temperature of a still tropical 31.8°C (89.2°F), showing a negligible variation from the month before. In June, Ko Lanta experiences a temperature dip to an average of 25.4°C (77.7°F) at night.

Heat index

During June, the heat index is evaluated at a blazing hot 46°C (114.8°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

The months with the highest humidity in Ko Lanta are May through November, with an average relative humidity of 85%.
