**Latest forecast guidance points to a minimum temperature of 13°C in Cape Town on September 7 as the most likely outcome, driven by clear skies, high pressure, and light winds enabling radiational cooling overnight.** Current observations show daytime highs near 25–27°C with minimal cloud cover persisting into the evening, consistent with model consensus for overnight lows around that threshold under stable anticyclonic conditions. This positioning reflects aggregated trader assessment of official guidance from agencies tracking surface observations and model runs, where 13°C aligns closely with expected cooling rates given dew points near 12–13°C and low humidity. Realistic challenges include stronger-than-forecast southeasterly winds or increased low-level moisture that could limit cooling and push the minimum above 14°C, though recent model agreement reduces the likelihood of significant deviation.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
