Pronóstico: Highest temperature in Amsterdam on August 17?

Platform comparison

Market context

Amsterdam's highest temperature on 17 August 2026 will be measured at the official Schiphol Airport weather station and resolved against the Daily Observations table on Weather Underground, which records sub-hourly readings rather than the rounded summary figures. This distinction matters: the Daily Observations table often captures peak temperatures that the Day High & Low section may not display with full precision, particularly during rapid warming or cooling cycles common in Dutch summer afternoons.

August in the Netherlands typically sees daytime highs between 22–26°C, though heat waves pushing into the low 30s occur roughly once per decade. The 17th falls mid-month, when Atlantic weather systems and continental air masses compete for influence over the Low Countries. Historical August records at Schiphol exceed 35°C, but such extremes require sustained high-pressure systems to establish themselves days in advance. The current 0% crowd probability suggests traders expect a relatively cool day or are pricing in uncertainty around the exact measurement methodology.

Traders should monitor European weather forecasting models from mid-August onwards, particularly the ECMWF and GFS outputs issued 10–14 days before the settlement date. Any significant high-pressure ridge building over Scandinavia or Central Europe in early-to-mid August would shift probabilities materially. Schiphol's location near the North Sea coast also means maritime influence can suppress afternoon peaks; onshore wind flow on the 17th would favour lower temperature ranges. The resolution window closes at 12:00 UTC, which may exclude the afternoon peak if readings continue past that point.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
