Trader consensus on Polymarket assigns an 84% implied probability to Jeddah's highest temperature reaching 37°C or higher on May 17, driven by the latest forecast models from global ensembles projecting daytime highs of 37-39°C under persistent clear skies. This positioning reflects early May's heat pattern, including a 41°C peak on May 6 amid a strengthening subtropical high-pressure ridge over the Arabian Peninsula, which suppresses convective activity and maximizes solar heating on the Red Sea coast. Jeddah's May climatological average high of 37°C provides historical baseline support, with low cloud cover and sea breezes offering minimal moderation risk. National Center for Meteorology updates expected in the next 24 hours could refine these trajectories ahead of resolution based on official airport observations.

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 King Abdulaziz International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/sa/jeddah/OEJN.
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.
