Market context

Busan’s outcome depends on the **highest observed temperature** at Gimhae International Airport, not the headline daily max, so the practical task for traders is to follow the station log as it updates through the day and into the overnight publication cycle. In late summer, Busan commonly posts highs in the high 20s to low 30s Celsius, with August climatology around 27°C average and typical highs near 30°C, which makes the market’s crowded pricing around 30°C and 31°C look anchored to ordinary warm-season conditions rather than an exceptional heat spike.[7][18][12][4]

For historical framing, August in Busan is usually hot and humid but is moderated by coastal flow; climatology sources put the month’s average high at about 84–87°F, while long-run August records can still reach the mid-30s Celsius on especially hot days.[7][12][18][6] That matters for a programmatic read: a bot would normally weight the distribution toward the low-30s Celsius band unless a heat warning, unusual synoptic pattern, or dry offshore wind setup raises the chance of a brief overshoot. Today’s 0% YES implies the market is either mispriced or waiting for the day’s live observations to validate an early consensus, so any model should distinguish forecasted air temperature from the settlement source’s recorded station maximum.[4][15]

The key catalysts are the morning forecast updates, any Korea Meteorological Administration heat or thunderstorm advisories, and whether cloud cover or rain suppresses the afternoon peak; current forecasts for Busan on 10 August point to a warm, showery, breezy day rather than a straightforward clear-sky maximum.[15][11][1] For a trading workflow, the useful trigger is the Wunderground daily observations feed itself: once the first datapoint for 11 August is published, later corrections no longer count, so automated monitoring should watch for the final August 10 station record rather than the day-high summary tile.[4]

Methodology

This page reviews Highest temperature in Busan on August 10? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Polymarket Review UK, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

Is this market available outside the US?
Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
Is Polymarket legal in the UK?
