**Current forecasts from multiple meteorological sources indicate a high of 18–20°C (64–68°F) for Cape Town on September 9, 2026, driven by moderate southerly winds and increasing cloud cover that limit daytime warming.** After several unusually warm days earlier in the week, including maxima near 30°C, cooler maritime air has arrived, consistent with typical spring patterns where average September highs range 18–20°C. Official model consensus and real-time observations show temperatures peaking in the late morning to early afternoon before declining, with dew points and humidity supporting limited further rise. Trader positioning heavily favoring 17°C or below reflects this cooling trend and the low likelihood of exceeding recent model runs, though small probabilities remain for brief spikes if winds weaken. Updated NHC-equivalent local guidance and hourly data releases through the afternoon will determine final resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 9 Sep '26.
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=fact
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.**Current forecasts from multiple meteorological sources indicate a high of 18–20°C (64–68°F) for Cape Town on September 9, 2026, driven by moderate southerly winds and increasing cloud cover that limit daytime warming.** After several unusually warm days earlier in the week, including maxima near 30°C, cooler maritime air has arrived, consistent with typical spring patterns where average September highs range 18–20°C.
