**Forecast models for Cape Town on September 25 point to a mild day with persistent cloud cover, scattered showers, and light-to-moderate northwesterly winds shifting southerly, limiting daytime heating.** Official and ensemble guidance from sources including the South African Weather Service and global models converge on a maximum near 19–21 °C, consistent with the market’s tight clustering around those outcomes. A cut-off low-pressure system and associated frontal activity have kept conditions unsettled after an unusually warm mid-September period (when highs reached 32 °C). The resulting stratiform cloud and intermittent precipitation reduce incoming solar radiation, while the marine layer from the adjacent Atlantic further caps temperatures. Historical September averages hover around 19 °C, providing a useful baseline against which current cooler, moister air stands out. Small differences among leading probabilities (20 °C at 24 %, 21 °C at 19.5 %, 19 °C at 16.5 %) reflect minor model spread in the exact timing and intensity of showers versus brief sunny breaks, plus uncertainty in how quickly winds veer and strengthen. Traders are therefore pricing genuine forecast uncertainty rather than a single dominant signal, with lower-probability tails (22 °C and above, or 18 °C and below) discounted because they would require atypical clearing or stronger onshore flow not currently indicated. Updated model runs and official briefings tomorrow morning remain the key near-term catalysts.

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.
