Recent meteorological forecasts for Istanbul on September 3 indicate a peak daytime temperature near 26–27°C under mostly sunny conditions, northeasterly winds of 10–15 mph, and minimal cloud cover, aligning with the market's strong preference for 26°C. Official model consensus from sources like GFS data and local observations shows afternoon highs stabilizing in this range, consistent with typical early-September climatology where daily maxima average around 27°C. Low precipitation risk and stable atmospheric pressure further reduce upside potential to 28°C or above, while overnight lows near 21°C limit any late-day rebound. Traders appear to weigh these verified model runs and real-time station readings heavily, though minor variations in exact peak timing or microclimate effects at official measurement sites introduce modest uncertainty reflected in the secondary 27°C probability.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=LTFM
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
