Recent model consensus from sources including the South African Weather Service and international ensembles points to a stable early-spring pattern over Cape Town, with mostly sunny conditions and light southerly to southwesterly winds limiting both daytime heating and nocturnal cooling for September 1. Forecast highs cluster between 18–19 °C, aligning with the market’s heaviest probability mass on those two outcomes; 19 °C edges ahead as several deterministic runs and ensemble means have trended 0.5–1 °C warmer in the past 48 hours. Historical climatology for early September shows a mean daily maximum near 18 °C, so the current guidance sits close to the long-term baseline with modest upside potential from clearer skies and reduced marine-layer influence. No major synoptic shift—such as a stronger offshore flow or approaching cold front—is indicated before resolution, keeping 17 °C and 20 °C as lower-probability tails.

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 1 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Recent model consensus from sources including the South African Weather Service and international ensembles points to a stable early-spring pattern over Cape Town, with mostly sunny conditions and light southerly to southwesterly winds limiting both daytime heating and nocturnal cooling for September 1.
