Forecast models from agencies like the Met Office and ECMWF indicate a mild early-summer pattern over the Netherlands on June 18, 2026, with daytime highs centered near 27–28°C under partly cloudy skies and light southwesterly flow, consistent with climatological averages for mid-June. This consensus, supported by recent observational trends showing gradual warming from 23–25°C baselines earlier in the month, underpins the market’s emphasis on 26–28°C outcomes as the most probable resolution thresholds. Minimal model spread and absence of heat advection or clear-sky amplification keep higher probabilities (29°C+) subdued, while typical North Sea moderation limits downside risk below 25°C. Traders monitor final afternoon observations from Amsterdam stations for any last adjustments before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 18 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Amsterdam Airport Schiphol Station, available here: https://www.wunderground.com/history/daily/nl/schiphol/EHAM.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Forecast models from agencies like the Met Office and ECMWF indicate a mild early-summer pattern over the Netherlands on June 18, 2026, with daytime highs centered near 27–28°C under partly cloudy skies and light southwesterly flow, consistent with climatological averages for mid-June.
