Highest temperature in Milan on August 20?

Platform comparison

Market context

On 20 August 2026, Milan's highest temperature will be recorded at Malpensa International Airport Station and measured in degrees Celsius. The market will resolve based on the Daily Observations table from Weather Underground rather than summary figures, establishing a precise resolution standard for what is fundamentally a meteorological measurement rather than a forecast exercise.

Milan's August temperatures have historically clustered in the 28–32°C range, with extreme heat events pushing above 35°C occurring roughly once per decade. The current 0% crowd probability suggests traders are either awaiting range options to be specified or treating this as a calibration market. August typically represents Milan's warmest month, with sustained high pressure systems from the Azores occasionally steering continental air masses northward into the Po Valley, creating conditions conducive to elevated readings. Comparable August days at Malpensa have recorded highs between 26°C and 37°C depending on synoptic patterns.

Traders should monitor European weather modelling outputs from mid-August 2026, particularly whether the North Atlantic Oscillation favours blocking patterns that would channel warm air into northern Italy. The Copernicus Climate Change Service and national meteorological services will issue seasonal outlooks in the months preceding the resolution date. Any significant heat dome formation across southern Europe in early-to-mid August could shift probability distributions substantially, as such systems frequently extend northward into the Alpine foothills where Milan is situated. The specific resolution methodology—using Daily Observations rather than Day High & Low summaries—creates a technical dependency on Weather Underground's data quality and station maintenance.

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.

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.

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.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

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.
