Highest temperature in Seoul on June 16?

Market context

On 16 June 2026, Seoul's highest temperature will be measured at Incheon International Airport Station and resolved against five temperature bands. The settlement window closes at midday UTC, meaning the final reading must be recorded before that point, though the actual daily high typically occurs in the afternoon local time (Seoul is UTC+9). This timing constraint creates a technical edge: traders must account for whether the airport's official recording captures the true peak before the market locks.

Seoul's June climate sits firmly in early summer, with historical highs clustering between 28–32°C during this period. The 0% crowd probability suggests traders are pricing near the lower boundary of the range, likely reflecting either a pessimistic seasonal read or uncertainty about which specific temperature band the market offers. Recent years show considerable volatility: June 2023 saw peaks near 30°C, whilst 2022 peaked at 31°C. Monsoon onset timing, typically late June, can suppress temperatures if low-pressure systems arrive early, though mid-June usually precedes the heaviest rainfall.

The key variable is whether a high-pressure system dominates the Korean peninsula in the days leading to 16 June 2026. Traders should monitor weather forecasts from the Korea Meteorological Administration and international models (GFS, ECMWF) from approximately 10–14 June, when five-day outlooks stabilise. Any early monsoon activation or tropical air mass intrusion would shift probabilities materially. The Incheon station's coastal location means sea-breeze effects can moderate afternoon peaks compared to inland Seoul readings, a factor often overlooked in casual temperature predictions.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
