What's happening in Seoul this week?

Seoul's week pivots on which palaces are open. Gyeongbokgung — the big one, with the guard-changing ceremony in the wide stone courtyard — closes every Tuesday. Changdeokgung, Deoksugung, and Changgyeonggung all close Monday. So Tuesday is your market and neighborhood day; Monday is your Gyeongbokgung day. The guard ceremony runs at 10am and 2pm (skip the 2pm slot in summer — you'll be standing on white gravel in full sun with no shade and the heat settles around your shoulders like a wool coat). Worth noting: the National Museum of Korea stays open every day and is free, which makes it a reliable fallback on whichever day the palaces lock up. If you're only seeing one palace, make it Changdeokgung and its Secret Garden — the canopy filters the light into green-gold patches on the moss, and the guided tour keeps the crowds moving so it never feels overrun.

Gwangjang Market operates daily, but the feel of the place shifts through the week. Weekday mornings are when the fabric merchants dominate — bolts of silk stacked floor to ceiling, the steady hum of sewing machines drifting from the upper floors, food stalls still setting up around 10am. By Friday afternoon the bindaetteok vendors are three-deep with locals stopping after work. Those mung bean pancakes come out of shallow oil with edges that crackle when you bite through — the inside stays soft and faintly earthy. Weekend mornings at Gwangjang are shoulder-to-shoulder by 11am, and the mayak gimbap line near the east entrance gets long enough that you'll question your commitment. Go weekday if you can. Namdaemun Market follows a similar arc but shuts most stalls on Sunday — hit it on a weekday morning for better prices on dried seaweed, sesame oil, and kitchenware. Noryangjin Fish Market runs around the clock, though the wholesale auction floor comes alive at 3am. For eating, go mid-morning on a weekday when the sashimi vendors are competing for attention and the raw fish cases haven't been picked over.

The neighborhoods run on different clocks. Hongdae — the university district west of Sinchon — is dead before noon and pointless on a weekday morning. Friday and Saturday nights it flips entirely: buskers set up in the main plaza around 7pm, the clubs on the back streets don't peak until midnight, and you'll hear everything from Korean indie rock to someone playing traditional gayageum with a loop pedal. The fried chicken and beer joints along Eoulmadang-ro stay packed until 2am. Weeknight alternative: Thursday in Euljiro, where converted printing-shop bars — tiny rooms, exposed pipes, the smell of old ink competing with craft beer — have become the city's most interesting drinking district without the weekend markup. Itaewon and Hannam-dong do weekend brunch culture; expect waits at any place with a line out the door on Saturday before 1pm. Bukchon Hanok Village, the traditional-house neighborhood between Gyeongbokgung and Changdeokgung, is best on a weekday morning before 10am. On weekends the narrow alleys fill with tour groups and the residents — who still live there — have posted signs asking visitors to keep quiet. Respect those signs.

Late April Seoul sits in a good stretch — daytime highs around 18–24°C, low humidity, and the cherry blossoms along Yeouido's riverbank path are likely fading to pink-white drifts on the pavement. Morning air still carries a bite around 8°C, so layer. Rain probability picks up through May; the real monsoon doesn't arrive until late June. The best weather days tend to cluster mid-week, Tuesday through Thursday, with weekend afternoons occasionally catching yellow dust blown in from the Gobi. Check the mise (미세먼지, fine dust) index on the Naver Weather app before planning outdoor time — if the AQI spikes above 150, make it a museum-and-subway day, not a palace-garden day. At the current rate of roughly 1,483 KRW to 1 USD, a bowl of budae-jjigae at a neighborhood spot in Mapo-gu runs about 9,000–11,000 KRW ($6–7), and a T-money transit card loaded with 20,000 KRW ($13.50) covers about four days of subway rides. That card also works on buses and at convenience stores, so load it at any subway station kiosk and stop thinking about small change.
