Recent official forecasts from sources including the Turkish State Meteorological Service and international models indicate mostly sunny conditions with northeasterly winds on August 31, supporting daytime maxima near 28°C after a cooler, showery period on August 29. Trader consensus favoring 26–27°C reflects model spread in peak timing, local station measurement variability, and lingering effects of northerly flow suppressing temperatures slightly below seasonal norms around 29°C. Clear skies and moderate humidity will allow strong solar heating, yet strengthening afternoon winds and proximity to the Bosphorus could cap the high. Updated ECMWF and GFS runs ahead of resolution on September 1 remain the key near-term catalyst for any shift in implied probabilities.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
