**Trader consensus on the Cape Town highest-temperature market heavily favors 17°C or below because real-time observations and official forecasts show the day’s maximum remaining at or below that threshold.** On September 9, 2026, Cape Town International Airport and other stations recorded afternoon temperatures around 15–17°C under overcast skies and persistent southerly winds of 15–25 km/h, consistent with a cool maritime air mass typical of early spring. Multiple forecast models (including those from the South African Weather Service and international guidance) projected daytime highs of 16–19°C but with limited insolation due to cloud cover and strong onshore flow, keeping actual peaks at the lower end of that range. This aligns with the broader September climatology of average highs near 18°C, though recent days had been warmer before the current regime shift. The near-certain market-implied probability reflects the strength of the observational data and model agreement at this late stage of the day. A realistic scenario that could still alter the outcome would require rapid clearing and reduced wind speeds allowing additional solar heating in the final hours, though current conditions make that improbable.

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.
