Pyeongchang weather in October

October is the clear winner: 18°C, dry, and the palace grounds turning colour by the end of the month. Skip July and August — that's monsoon plus 30°C plus humidity, and the score doesn't exaggerate it.

South Korea's forum is blunt that July nationwide, Pyeongchang's mountain setting included, means hot, muggy days with rain showing up roughly every few days rather than every single one. Forum regulars specifically recommend an umbrella over a raincoat, since you'll sweat right through plastic in this humidity. A run of several rainy days in a row isn't unusual during the wetter stretch of the month, but posters were also clear it's not an all-day downpour every time - more a mix of humid, overcast stretches punctuated by heavier rain.

Forum posters describe January here as bitterly cold but reliably dry, with clear blue skies common and wind - rather than precipitation - named as the main day-to-day discomfort on the slopes. Posters note that when natural snowfall runs short, resorts lean heavily on snowmaking to keep runs open, since sub-zero temperatures make artificial snow production reliable through the month. Posters planning a trip around the Korean New Year (late January, on the lunar calendar) flag possible service disruptions to buses and some resort operations during the holiday itself, worth building slack into an itinerary around. Overall, posters treat January as prime, dependable ski season here, with cold rather than crowds or unreliable snow being the main thing to pack for.
