Highest temperature in Seoul (Incheon) on August 15?

Platform comparison

Market context

On 15 August 2026, Seoul's highest temperature will be measured at Incheon International Airport Station and categorised into temperature bands. The market currently shows 0% probability across all ranges, suggesting traders are uncertain about which bracket will contain the day's peak reading or are awaiting more concrete seasonal forecasts as the date approaches.

Seoul experiences peak summer heat in mid-August, with historical August averages around 29°C and daily highs frequently exceeding 32°C. Data from the Korea Meteorological Administration shows that 15 August typically falls within Seoul's hottest fortnight, though extreme heat events pushing temperatures above 35°C occur irregularly—roughly once every three to five years during this period. The 0% crowd probability likely reflects the market's nascent stage rather than genuine uncertainty about whether measurable heat will occur; traders are probably waiting for seasonal pattern updates and long-range forecasts to materialise before committing positions.

Traders should monitor the Korean Meteorological Administration's seasonal outlooks released in June and July 2026, which typically provide confidence intervals for temperature anomalies during the latter half of August. El Niño or La Niña conditions developing through spring 2026 will influence whether the summer proves warmer or cooler than the 30-year baseline. Additionally, the specific resolution methodology—relying on Weather Underground's Daily Observations table rather than summary figures—means traders should familiarise themselves with how Incheon station reports data, as discrepancies between observation records and headline figures occasionally occur.

UK Frequently Asked Questions

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.

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.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
