Recent forecasts from multiple models show Istanbul's August 29 maximum likely near 25°C, with a modest spread reflecting uncertainty in cloud cover and shower timing. A northerly flow has already lowered temperatures after recent 29–30°C readings, while scattered showers and intermittent cloud expected through the period limit surface heating and reduce peak values relative to August climatology of 28–29°C. Ensemble guidance from sources such as the Met Office and regional models clusters between 24–27°C, with light precipitation risk on the 28th–29th creating the main variable that separates the closely matched 24°C and 25°C market leaders. Updated model runs and official station data the morning of the 29th will refine the final outcome.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
