The tight race between 10°C (28%) and 11°C (28%) for London's highest temperature on March 28 stems from the latest Met Office ensemble forecasts, which converge on maxima in this range under a transitional weather regime. A persistent high-pressure ridge ushering cool northerly airflow has suppressed recent spring temperatures below the March climatological average of 11.5°C at Heathrow, but an incoming Atlantic frontal boundary promises subtle mildening and patchy cloud breaks by mid-afternoon, potentially tipping peaks to 11°C. Model spreads (±1-2°C across ECMWF and UKMO runs) highlight uncertainty from variable insolation and urban heat island effects, differentiating these outcomes while sidelining warmer 12°C+ bets at 21% amid low-confidence sunshine totals.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/gb/london/EGLC.
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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
