June weather forecast
Tonjong, Indonesia

June, the first month of the winter in Tonjong, is also a moderately hot month, with an average temperature varying between 29.6°C (85.3°F) and 22.1°C (71.8°F).

Temperature

The arrival of June records an average high-temperature of a warm 29.6°C (85.3°F), closely related to the 30.3°C (86.5°F) observed in May. During June, the temperature is averaged to a low of 22.1°C (71.8°F) at night.

Heat index

In June, the average heat index is computed to be a sweltering 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
When referencing the heat index, its values are suitable for shady environments and light 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 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In June, the average relative humidity is 82%.

Rainfall

In June, the rain falls for 18 days. Throughout June, 91mm (3.58") of precipitation is accumulated. Throughout the year, there are 268.1 rainfall days, and 2169mm (85.39") of precipitation is accumulated.

UV index

February through June, September, October and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for average individuals.
Note: In June, the UV index of 7 transforms into the following advice:
Resist extreme sun exposure. Guarding against solar damage is essential. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
