Will the highest temperature in Seoul be 21°C or higher on April 24?

Analysis

I'm usually the first to poke holes in weather hype. But when the Korea Meteorological Administration is calling 24°C at Incheon Airport with clear skies, and every major global model — ECMWF, GFS, the lot — is telling the same story, that's not hype. That's convergence. The 21°C threshold isn't a knife-edge call here. You need to be three full degrees wrong before this unravels. Seoul was already touching 18°C earlier this week on the back of a high-pressure ridge and southerly winds — the warmth is already baked in and building. Yes, the sea breeze at Incheon can shave a degree or two off the peak. Yes, afternoon cloud cover is always a wildcard. But for the forecast to miss badly enough to matter, you'd need an unpredicted meteorological reversal that zero serious models are flagging right now. When the sceptic in me checks the evidence and still can't find a credible bear case, that tells you something. Back YES — the margin of safety here is too wide to bet against.
