Forecast models indicate a southeasterly flow advecting warmer continental air toward Amsterdam on August 27, supporting daytime highs near 27–28°C under partly to mostly cloudy skies. Increasing low- and mid-level moisture favors afternoon convection and isolated thundershowers, which could limit peak insolation and cap temperatures if showers arrive before late afternoon. Ensemble guidance shows modest spread around the diurnal maximum, with 26–29°C outcomes all plausible depending on cloud timing and boundary-layer mixing. Historical August averages near 20–22°C provide context for the elevated but not extreme warmth, while the tight market distribution around 27°C reflects traders weighting the balance between radiative heating and potential convective suppression.

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.
