Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS), aligned with China Meteorological Administration guidance, have converged on an overnight low of 23°C for Shanghai amid persistent Meiyu (plum rain) conditions characterized by extensive cloud cover, high humidity, and light winds that limit radiational cooling. These stable atmospheric conditions, typical for mid-June in the region, suppress temperature variability and anchor the minimum near the climatological average for the date. Trader consensus has rapidly consolidated around this outcome as model agreement tightened within the final 24–48 hours. A sudden reduction in cloud cover or shift in steering winds could allow greater nighttime cooling or slight warming, potentially shifting the low by 1–2°C and reopening lower-probability brackets.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 17 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD.
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.Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS), aligned with China Meteorological Administration guidance, have converged on an overnight low of 23°C for Shanghai amid persistent Meiyu (plum rain) conditions characterized by extensive cloud cover, high humidity, and light winds that limit radiational cooling.
