Seoul Window: Not a Travel Blog — Seoul Read Through Data
Search for travel information long enough and you start reading the same sentences. “Ten places you must visit.” “The local-only restaurant.” What you actually want to know is usually duller than that. Is it cold out right now? Will there be a queue at this hour? At today’s rate, how much should I change?
Seoul Window sits on the duller side of that line. Its own line for it: Not another travel blog. Seoul travel, decoded by data.
- The Seoul Board — weather, air quality, district crowding and exchange rates on one screen.
- 24-hour live stream — a Seoul street in real time, with time and temperature on screen.
- Seoul Pulse — a short data briefing each morning, a digest each week.
- 400+ guides — 12 districts across eat, do, beauty and shop, in four languages.
- No sign-up, no app, free.
The Seoul Board — the city as it is right now
The board sits at the centre of the home page: the current state of Seoul, laid out as tiles.
| Area | What it shows | Updates |
|---|---|---|
| Weather | Current temperature, tomorrow's forecast, sunrise/sunset | Hourly |
| Air & UV | PM2.5, UV index | Hourly |
| District crowding | Nine major Seoul districts, live | Hourly |
| Incheon Airport | T1 & T2 arrival/departure passenger forecasts | Hourly |
| Exchange rates | The won against 30+ currencies | Daily |
| Countdowns | Holiday D-days, last trains at Hongik Univ. and Seoul Station | Always on |
| Rising searches | Travel keywords trending in Korea right now | Daily |
A period toggle (NOW / 7D / 30D / 90D) means you can read how today compares to normal, not just what today is. “It’s busy” becomes “it’s busier than this week’s average.”
24 hours live — the street, not the forecast
Above the board runs a live stream of a Seoul street, 24 hours a day, with the current time and temperature on screen and a broadcast-style ticker underneath carrying crowding and a one-line observation.
What this replaces in trip planning isn’t the forecast — it’s the what-to-wear decision. “High of 18°C” doesn’t tell you whether you need a jacket. The sleeve lengths on screen do.
Seoul Pulse — a data briefing each morning
Yesterday’s measurements (peak crowding by district, temperature, fine dust), today’s outlook, and any notable currency move, bundled into a short briefing on weekday mornings. Sunday evening brings a digest of the week.
It reads less like an article and more like a numbers note. If you’re mid-trip, it’s the sort of thing to skim over breakfast and adjust the day’s route around.
400+ guides, four languages
It isn’t only indicators. More than 400 area and topic guides have accumulated, all published in English, Japanese and Chinese (Simplified and Traditional).
- Districts: Hongdae, Myeongdong, Seongsu, Gyeongbokgung, Gangnam, Jamsil, Itaewon, Dongdaemun, Yeouido, Jongno, Yeonnam, Sinchon — 12 in total

The texture runs like this — eight personal colour analysis studios with prices, session lengths and language support, how Life4Cut, Photoism and Haru Film differ in colour tone, measured subway crowding by station and hour. More tables and numbers than impressions.
Four things that matter for a hanbok day
If you’re reading this site, your purpose is fairly specific. Narrowed to what touches a hanbok day directly:
- The live stream — decides what goes under the hanbok. A rented hanbok layers over the clothes you arrive in, and that one decision sets how the whole day feels.
- Gyeongbokgung crowding — decides your photo hour, and gives you a reason to skip the guard-ceremony window and weekend afternoons.
- PM2.5 — decides whether wide shots are worth it. On a hazy day, swap the pond-side Gyeonghoeru frame for closer portraits.
- Sunset time — tells you whether your return deadline and the golden hour overlap.
Guides for the palace neighbourhood are collected on the Gyeongbokgung area page. The half-day course built backwards from the guard ceremony times pairs particularly well with a typical 2–4 hour rental.
We’ve written the morning routine version of all this separately, in what to check on the morning of your hanbok day.
In short
Seoul Window handles the city’s live state and the neighbourhood guides; this site handles the price lists, included items and closing days for 28 hanbok shops around Gyeongbokgung and Bukchon. There’s almost no overlap, and between the two, nothing much about planning a hanbok day gets missed.
Frequently asked questions
What is Seoul Window?
It's a Seoul travel information site for international visitors. Instead of review-style blog posts, it puts live indicators — temperature, district crowding, air quality, exchange rates — on a single screen called the Seoul Board, and adds more than 400 area and topic guides on top. Available in English, Japanese and Chinese (Simplified and Traditional).
Can I check Seoul's live conditions for free?
Yes. seoulwindow.com needs no sign-up and no app. The Seoul Board's weather, air quality, district crowding, exchange rates and last-train countdowns, plus the 24-hour live stream, are all free to view.
Can I see how crowded Seoul is right now?
Current congestion for nine major Seoul districts is refreshed hourly from the city's real-time urban data. A NOW / 7D / 30D / 90D toggle lets you compare right now against the recent baseline.
Which parts are most useful for a hanbok trip?
The live stream for deciding what to wear under the hanbok, Gyeongbokgung crowding for picking a photo hour, PM2.5 for deciding whether wide shots will work, and sunset time for lining up your return deadline with the golden hour. The Gyeongbokgung area page collects the guides for that neighbourhood.
