Highest temperature in Warsaw on July 27?

Platform comparison

Market context

On 27 July 2026, the highest temperature recorded at Warsaw Chopin Airport will determine which range this market settles into. The settlement source is Wunderground's historical weather data for that specific station and date, with the final reading locked in at 12:00 UTC. Warsaw's July climate typically peaks between 23–28 °C, though heat waves can push readings above 30 °C; the 0% crowd probability suggests traders are either uncertain about which range will resolve or awaiting clearer market definition.

Historical July temperatures at Warsaw Chopin show considerable year-to-year variance. Between 2015 and 2024, peak daily highs in late July ranged from 20 °C to 31 °C, with an average around 25 °C. The 2023 European heat wave saw Warsaw reach 32 °C in mid-July, demonstrating that extreme outcomes, whilst uncommon, occur roughly once per decade. This distribution should anchor baseline expectations; the current 0% reading likely reflects ambiguity about the specific temperature brackets offered rather than certainty about weather itself.

Traders should monitor European weather forecasts from mid-July 2026 onwards, particularly pressure systems tracking across the continent. The Polish Institute of Meteorology (IMGW) publishes extended outlooks roughly two weeks ahead; any Atlantic ridge or African heat transport would signal elevated probability for higher ranges. Wunderground's historical data feed remains the sole authoritative source, so confirmation of station operability and data availability matters operationally. Settlement occurs at noon UTC, meaning any afternoon temperature spike on the 27th will be captured in the final reading.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Kalshi Legit has a different geo footprint.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legit exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
