June is characterized by further escalation of the rain season in
Luang Prabang. The amount of rainfall soars to its annual peak at 258mm (10.16") preparing the city for prolonged wet and humid conditions. The drop in temperatures continues and lower temperatures make the month relatively comfortable, despite the high amount of rainfall. The city witnesses the longest daylight duration for the year, though fewer sunshine hours due to increased cloud cover. The UV index stays at its maximum, requiring regular sun protection for those venturing outdoors.
Temperature
Transitioning into June, Luang Prabang records an average high-temperature of a still tropical 32.4°C (90.3°F), almost identical to
May's 33.8°C (92.8°F). June is noted for a mean low-temperature of 24.5°C (76.1°F).
Heat index
The heat index for June is appraised at a blazing hot 48°C (118.4°F).
Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Heat index evaluations are typically in the context of light winds and shaded environments. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Take all required precautions, as unprotected skin and eyes can burn in minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Even on a cloudy day, a sunscreen with at least a 30 SPF should be applied generously and frequently reapplied, including after a swim or outdoor exercise.
