Recent forecast guidance from regional models points to a mild spring day in Qingdao shaped by the moderating influence of the adjacent Yellow Sea, which typically anchors mid-May daily highs near 19–21 °C. Subtle differences among leading outcomes hinge on expected cloud cover, sea-breeze timing, and the strength of any weak frontal boundary crossing the Shandong Peninsula; stronger onshore flow would favor the 18–19 °C band, while clearer skies and lighter winds could push the maximum into the low 20s. Historical observations from the China Meteorological Administration show this range accounts for the majority of May 18 readings, leaving only modest probability for excursions beyond 22 °C or below 17 °C. Updated model runs and official station data issued tomorrow morning will refine these narrow distinctions ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Qingdao Jiaodong International Airport Station in degrees Celsius on 18 May '26.
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 Qingdao Jiaodong International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/qingdao/ZSQD.
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.Recent forecast guidance from regional models points to a mild spring day in Qingdao shaped by the moderating influence of the adjacent Yellow Sea, which typically anchors mid-May daily highs near 19–21 °C.
