Highest temperature in Busan on August 1?

Platform comparison

Market context

Busan’s early-August weather is usually hot, humid and rain-prone, with climate normals pointing to average highs in the high 20s to around 30°C and frequent muggy afternoons. That makes the market’s 0% YES price look anchored to the idea that the day’s top reading at Gimhae Airport will stay inside a fairly ordinary summer band rather than jump into a rare extreme. [4][11][14]

The main historical frame is that Busan can spike well beyond its average on isolated heatwaves: Anadolu reported the city reached 38.8°C on 29 July 2025, described as its highest temperature in 122 years, while climatology sites note August is the hottest month and can produce days in the mid-30s °C. [17][18][19] By contrast, the typical August profile is much lower, with average highs around 87°F/31°C and a broad seasonal range that still leaves room for a sharp upside surprise if hot, dry air dominates the day. [1][4][6]

For traders, the key catalyst is the synoptic setup over south-eastern Korea: whether a heat ridge persists, how much maritime cloud or afternoon rain develops, and whether any heat advisory or typhoon-related rain changes the day’s maximum before the settlement window closes. Recent reporting on record heat in the region suggests the market is currently leaning on the possibility of a continued hot spell, but the actual settlement will depend on the highest reading logged at Gimhae International Airport rather than city-wide impressions or forecasts.

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
