Seoul weather facts every pet owner should know

Seoul swings roughly 50 degrees between seasons: January highs average just 35.8F while August reaches 86.0F, so dogs here need both a winter coat plan and a summer heat plan.
January lows average 22.1F, inside the 20 to 32F caution band, and the record low of -9.6F (observations since 1907) means wind chill can push walks into dangerous territory fast.
Seoul averages about 24 snow days a year, roughly 7 of them in January alone, so road salt rinses and paw checks are standard winter routine.
The record high of 103.3F came in August, and the East Asian monsoon in June and July adds humidity that makes an 84.2F July afternoon feel far hotter to a dog.

Seoul pet weather questions

January lows average 22.1F, inside the 20 to 32F caution band, and anything below 20F is dangerous for most dogs. Keep December through February walks short, coat small and senior dogs whenever it is below 45F, and watch for ice on sidewalks.

Yes. August averages a 86.0F high, past the 82F risky band, the record is 103.3F, and June to July monsoon humidity makes it feel hotter still. Shift to dawn walks and keep flat-faced breeds indoors on the muggiest afternoons.

Seoul averages about 24 snow days a year, with roughly 7 in January, and sidewalks get salted heavily. Rinse or wipe paws after every winter walk, consider booties for long outings, and remember January's 35.8F average high means snow often lingers.
