June weather forecast
Medan, Indonesia

Despite a decrease in rainfall from May to June, the overall climate remains predominantly warm and humid. The high temperatures, coupled with humid conditions, make it integral to stay hydrated throughout the day. Being a coastal city, Medan isn't far from pleasant breeze blowing from the sea in the evenings.

Heat index

For June, the heat index is computed to be a burning hot 48°C (118.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of 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 especially vital to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
