Recent forecasts from global and regional models indicate persistent northwesterly flow and widespread cloud cover will cap daytime heating in Cape Town on September 15, favoring a maximum near 16–17 °C rather than the seasonal 18 °C average. A passing trough is expected to deliver steady rain and gusty winds that enhance mixing and limit solar insolation, keeping surface temperatures suppressed throughout the afternoon. Ensemble guidance shows limited spread around this cooler solution, with only modest upside potential if breaks in cloud allow brief warming. Traders therefore assign the highest implied probabilities to 17 °C and 18 °C, reflecting the balance between the dominant cool-air advection and residual uncertainty in exact cloud timing and wind strength ahead of final model updates.

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.
