Highest temperature in Busan on August 6?

Platform comparison

Market context

Busan’s hottest reading at Gimhae International Airport on 6 August will be set by the day’s maximum temperature, not the noon snapshot, so programmatic traders usually model it as an intraday extremes problem: combine the forecast distribution, local timing of the heat peak, and the settlement source’s airport station rather than city-wide averages. August climatology puts Busan’s typical high around the high 20s to low 30s °C, with forecast services showing around 31°C for the day and an upper range near 33°C, which leaves the market concentrated in a relatively narrow band unless an anomalous surge develops.[1][12][16]

Recent comparable heat events matter because Busan has already printed extreme values well above seasonal norms in the current regional pattern. South Korea set a national record of 42.5°C in Yangsan during the latest heatwave, while Busan itself reached 38.8°C in a prior record episode, its highest temperature in modern observations; that history frames why the market is best read as a tail-risk check rather than a simple “summer in Busan” trade.[2][3][14] A 0% implied probability for a YES threshold typically signals either a very high target range or a crowd discount on the chance of a record-level outcome, which can be useful for bots that compare forecast highs against historical station maxima and update continuously as new runs arrive.[18]

The main catalysts are the evolving heat advisory picture, any shift in regional wind or cloud cover, and whether convective rain interrupts the afternoon maximum; these are the variables that move the intraday peak more than the morning temperature does. Traders watching for automation should monitor forecast revisions, local met-office alerts, and the actual hourly path at Gimhae Airport, because a high that looks reachable in the morning can be capped quickly if marine cloud, rain bands, or a sea-breeze shift arrives early.[1][19]

Methodology

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

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.
