Recent forecast model consensus from agencies including the UK Met Office indicates a northerly airflow will bring cooler maritime air to Istanbul on August 28, with daytime highs peaking near 24°C amid light showers transitioning to partly cloudy conditions. This represents a notable drop from recent 28–30°C readings, driven by increased cloud cover and precipitation chances that suppress solar heating while sustained winds enhance mixing. Historical August averages near 27–29°C underscore the anomaly, with multiple model runs aligning on maximum temperatures between 23–25°C and low odds of extremes. Updated guidance and any late shifts in steering patterns or rainfall timing remain key variables ahead of market resolution.

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.
