Recent forecasts from sources including the Met Office and AccuWeather point to a maximum of 26–27°C in Amsterdam on August 27, 2026, aligning closely with the market’s leading outcomes at 39% and 29% implied probability. Late-August climatology features declining solar insolation and a shift toward more maritime air masses, keeping typical highs near 20–22°C, but current model guidance shows a modest positive anomaly driven by southerly flow and limited cloud cover before potential thundery showers develop. Early-month heat spikes above 30°C have given way to stabilization in the mid-20s, with ensemble spreads favoring outcomes between 25–28°C. Resolution hinges on official KNMI observations, and any late-model shift in boundary-layer moisture or wind direction could narrow the distribution further toward the 26–27°C cluster.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Amsterdam Airport Schiphol Station in degrees Celsius on 27 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eham
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent forecasts from sources including the Met Office and AccuWeather point to a maximum of 26–27°C in Amsterdam on August 27, 2026, aligning closely with the market’s leading outcomes at 39% and 29% implied probability.
