**Strong trader consensus around 23°C for London's highest temperature on August 30 stems from consistent Met Office and ensemble forecasts projecting a daytime maximum of 22–23°C under mostly fine conditions with sunny intervals, broken cloud, and moderate southwesterly winds.** Current observations and short-range model runs show temperatures peaking near this level by afternoon, aligning closely with late-August climatological averages for the region without significant heat advection or clear-sky amplification. Resolution hinges on official maximum readings, which rarely deviate substantially from these guidance values on settled days. Only unexpected intensification of afternoon showers or localized measurement anomalies could realistically push the outcome outside the narrow 22–24°C band.

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=eglc
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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.
