Weather in July

July retains the monsoon season momentum from June in Phuket. The main highlight is the high rainfall, consistent at 258mm (10.16"), despite constant temperatures. With fewer daylight and sunshine hours, tourists and locals alike must plan outdoor activities around erratic rain showers. However, the warmth of the sea remains a constant attraction. One would expect similar weather conditions while venturing into August.

Temperature

Transitioning from June to July, Phuket observes an average high-temperature of a still tropical 32°C (89.6°F), differing subtly from the previous month. In Phuket, July is marked by an average low-temperature of 25.1°C (77.2°F).

Heat index

In July, the heat index is estimated at a blistering 44°C (111.2°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Know that the heat index computations account for shaded terrains and slight winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
