Market context

Seoul's weather on 13 June 2026 will be measured at Incheon International Airport, with traders currently assigning zero probability to any outcome. This reflects the market's nascent state rather than meteorological certainty; early-stage weather contracts often display sparse liquidity and extreme probability distributions until forecasts solidify within the settlement window.

Historical temperature records for Seoul in mid-June show consistent patterns. The city averages highs of 26–28°C during this period, with extremes ranging from 22°C in cooler years to 32°C during heat waves. The 0% crowd probability suggests either minimal trading activity or a technical issue with market initialisation, as comparable weather markets typically reflect baseline seasonal expectations even months in advance. Cross-platform comparison data remains unavailable at present, though traditional weather forecasters and meteorological services will publish increasingly precise outlooks as June 2026 approaches.

Traders should monitor the Korean Meteorological Administration's seasonal forecasts and any El Niño or La Niña developments that could shift regional temperature patterns. The settlement window closes at 12:00 UTC on 13 June, requiring resolution data from Wunderground's historical records for Incheon station. Meaningful trading activity will likely emerge in May 2026 when 10–14 day forecasts become actionable; current odds divergence reflects the contract's distance from settlement rather than disagreement among forecasters.

Methodology

This page reviews Highest temperature in Seoul on June 13? across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at Best Prediction Markets UK — the application we operate, where you trade directly against the Polymarket order book at 0% fees.

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.
