June weather forecast
Bukit Mertajam, Malaysia

In June, Bukit Mertajam witnesses fewer rainfall days pitching down from 26.6 in May to 20.6 in June. This reduction is a warm welcome for locals and tourists alike anticipating outdoor excursions. Despite this, the persistent high temperatures render the overall climate humid. Evenings in the city turn cool and comfortable, allowing for leisurely walks and night market exploration. The weather in June impressively balances the scales between sun and rain, offering a fulfilling tropical experience.

Temperature

The onset of June brings with it an average high-temperature of a still tropical 32.6°C (90.7°F), showing a negligible variation from the month before. Bukit Mertajam reports an average nighttime low-temperature of 24°C (75.2°F) in June.

Heat index

The heat index value during June is estimated at a life-threatening hot 45°C (113°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

February, June through August, with an average relative humidity of 77%, are the least humid months in Bukit Mertajam.

Note: The maximum UV index, 7 during June, leads to the following recommendations:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
