Highest temperature in Amsterdam on July 31?

Platform comparison

Market context

Amsterdam Airport Schiphol’s highest temperature on 31 July will be decided by a single afternoon reading, and the market’s 0% YES probability implies traders see an outcome above the implied band as extremely unlikely. July in Amsterdam is usually mild rather than hot: climate summaries cluster around average highs of roughly 21–22.5°C, with typical daily highs in the low 20s and only occasional spikes into the high 20s or low 30s.[1][7][8][10][11][13] That makes the market most sensitive to whether conditions stay close to seasonal norms or whether a short-lived warm plume pushes the day well above average.

For framing, comparable hot July outcomes in Amsterdam have been rare rather than routine, with published records showing the city’s extreme summer readings are far above its mean but not the norm.[14] In a regulation context, German GlüStV rules matter because they can restrict access for Germany-based users and require compliant onboarding, while US CFTC reach is relevant where a venue is treated as offering event contracts to US persons. For this specific market, “no-KYC up to $1,500” means smaller-volume participation may be available with lighter identity checks, but access can still be limited by jurisdiction, sanctions screening, payment rails, and exchange policy.

The main catalysts are weather-model shifts for the Benelux region, updated Schiphol forecasts, and any late-day change in cloud cover, wind direction, or precipitation that affects the afternoon maximum. A warm, dry signal from local forecasts would support a higher terminal temperature, while drizzle or stronger onshore flow would cap the high; one current forecast source shows a warm, cloudy day with a high near 26°C and a modest drizzle risk, illustrating how sensitive the reading is to small changes in the setup.[3] Traders should also watch the exact settlement source, because the market resolves to the highest temperature recorded at Amsterdam Airport Schiphol Station on Wunderground, not a city-wide average or forecast headline.
