Seoul experienced 22 tropical nights this July alone, the most for the month in 117 years.

Seoul's summer nights continue to stay hot and longer than usual.

At least 22 tropical nights were recorded in Seoul this July.

That's the longest period for the month in 117 years since related data first began to be compiled in 1908.

A tropical night refers to when the overnight low ---between 6 PM and 9 AM the next day ---does not drop below 25 degrees Celsius.

The previous record for the longest stretch of tropical nights in July was set in 1994, with 21.

But with one more day left till August in Korea, this year's record may climb further.

Adding to the heat, Seoul also logged its highest-ever overnight low for July on Wednesday into Thursday at 29-point-3 degrees.

The previous was 29-point-2 degrees, seven years ago, according to the Korea Meteorological Administration.

"The Tibetan and North Pacific high-pressure systems have overlapped over Korea, trapping heat in the atmosphere. Hot, humid air from the south is also being drawn in, while intense sunlight continues, making scorching days and tropical nights persist."

Asked whether this trend may continue due to climate change, the KMA said it's hard to predict as tropical nights are largely driven by variables including complex pressure patterns in the atmosphere.

Still, the weather agency forecasts tropical nights to continue for the time being, although some rain is expected after August 6.

The authorities are advising people to take precautions against heat-related illnesses, including keeping indoor temperatures and humidity moderate, ensuring proper ventilation, staying hydrated, and doing light exercises before bed for a good night's sleep.
