Highest temperature in Amsterdam on July 30?

Platform comparison

Market context

Amsterdam Airport Schiphol’s peak temperature for 30 July will settle against Wunderground’s daily history page, so the market is really about the day’s one-off high rather than the afternoon average. The crowd is still split across the mid-20s, with 25°C and 26°C both leading at 21%, while 0% on the current 0% YES framing implies the book is pricing no material chance of landing in the specified range as structured.[1]

For context, Amsterdam’s July climate usually sits in the low 20s Celsius, with daily highs around 21–22°C and only limited frequency of very hot days; a 30 July high in the mid-20s is therefore warmer than normal but not extreme.[5][8][9] Recent history matters too: Amsterdam has posted much hotter late-July readings in exceptional years, including 35.8°C on 1 July 2025 and mid-30s temperatures in 2018–2019, which shows the tail risk is real even if the distribution is centred lower.[12][13]

The main catalysts are the same-day forecast updates and the actual afternoon heating profile at Schiphol, where coastal influence can cap extremes if cloud, wind or sea-breeze effects arrive early. Traders watching book depth should also remember that this market is funded by payment rails rather than pure speculation: easier deposits through Klarna or SEPA, plus quicker withdrawals via USDC, typically improve turnover when weather risk is close to event time, while slower on-ramps can leave the book thinner until late prints force repricing.
