Highest temperature in Seoul on June 24?

Active sub-markets

Market context

On 24 June 2026, Seoul will experience its peak daily heat, with the highest temperature recorded at Incheon International Airport determining the outcome of this prediction market. The crowd-implied probability of a “YES” resolution sits at 0%, suggesting traders believe the temperature will fall outside the specified range. This stance contrasts sharply with historical patterns: June in Seoul typically sees daily highs rising from 77°F to 81°F (25°C to 27°C), rarely dipping below 68°F (20°C) or exceeding 87°F (31°C)[1]. Just days earlier, on 19 June 2026, Seoul hit 91°F (33°C), marking the highest temperature in the current period[2]. Such recent extremes align with broader trends, as 59 of 97 South Korean weather stations recorded record June highs between Saturday and Monday this week[5].

Traders should monitor updates from Wunderground, the official resolution source, and watch for any sudden shifts in the North Pacific high-pressure system, which drives summer humidity and heat in Seoul[4]. Analyst consensus, based on AccuWeather’s June 2026 forecast, projects daily highs between 82°F and 93°F (28°C–34°C), with an average high of 87°F (31°C)[8]. This range overlaps with the all-time Korean heat record of 41.0°C (105.8°F) set in Hongcheon, though Seoul itself has historically peaked near 35°C (95°F)[3][4]. Divergence exists between sportsbook lines, which may price in a higher chance of extreme heat, and the prediction market’s 0% implied probability, indicating a meaningful gap in market sentiment. No formal announcements are expected before the settlement window ends on 24 June 2026 at 12:00 UTC, but real-time Wunderground data will be critical.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
