June, the first month of the summer in
Nong Khai, is still a tropical month, with an average temperature fluctuating between 24.9°C (76.8°F) and 33°C (91.4°F).
Temperature
Nong Khai experiences a subtle adjustment in high-temperatures to a still hot 33°C (91.4°F) with the onset of June, maintaining near parity with
May's 34.2°C (93.6°F). Throughout June, Nong Khai records an average temperature of 24.9°C (76.8°F) at night.
Heat index
During June, the heat index is computed to be a life-threatening hot 50°C (122°F).
Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Heat index data is primarily for areas with shade and subjected to light winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Take all critical precautions, unprotected skin might burn swiftly. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise.
