South African Weather Service model ensembles currently project a daytime maximum near 20°C for Cape Town on May 18 under typical autumn southwesterly flow from the Atlantic, with light to moderate winds limiting rapid warming. This places the market’s leading 20°C and 21°C outcomes in near parity because afternoon cloud cover variability—common in the post-frontal regime—can suppress solar heating by 1–2°C or allow clearer skies to push peaks slightly higher. Historical May maxima at Cape Town International Airport average 17–20°C, providing context for the narrow 19–22°C spread in trader-implied odds. Final resolution hinges on intraday observations from official stations, with any unexpected clearing or strengthening onshore breeze able to shift the exact threshold within the 48-hour window.
