Weather in August

August presents an increase in rainfall from 97mm (3.82") in July to 107mm (4.21"), marking the peak of the wet season in Bukit Mertajam. Despite this, the city carries a warm and humid atmosphere throughout the month. The sunlight hours exhibit a slight decrease from July, yet offering adequate time for outdoor activities. The consistent sea temperatures across the month facilitate water-based activities. The increase in rainfall is well-compensated by the persistent warmth and humid climate.

Temperature

Bukit Mertajam experiences a transition to a still tropical 32.2°C (90°F) in average high-temperatures with the arrival of August, not greatly differing from July's 32.1°C (89.8°F). Nighttime temperature experiences an average drop to a moderately hot 23.9°C (75°F) in August.

Heat index

August's mean heat index is evaluated at an extremely hot 44°C (111.2°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
