Recent model consensus from sources like the UK Met Office and BBC points to a maximum of 20–22°C in Warsaw on August 19, with 21°C edging forecasts due to modest daytime heating under variable cloud. A broad Atlantic trough is advecting cooler maritime air northward, limiting strong insolation and promoting light showers or overcast conditions that cap surface warming. Boundary-layer mixing and light southwesterly flow further moderate peaks, keeping values near or slightly below late-summer climatology. Small differences among 20°C, 21°C, and 22°C hinge on exact cloud timing and any brief clear spells allowing extra solar input; stronger ridging or delayed frontal passage could push readings higher, while earlier precipitation would favor the lower end. Trader odds reflect this narrow scientific uncertainty window two days out.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Warsaw Chopin Airport Station in degrees Celsius on 19 Aug '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 Warsaw Chopin Airport Station, available here: https://www.wunderground.com/history/daily/pl/warsaw/EPWA.
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.
