August weather forecast
Bukit Mertajam, Malaysia

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.

The arrival of August is marked by an average high-temperature of a still hot 32.2°C (90°F), bearing a close resemblance to July. An average temperature of 23.9°C (75°F) is recorded during the nights in August.

Heat index

August's mean heat index is estimated at an extremely hot 44°C (111.2°F). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
