Recent forecast models from the South African Weather Service indicate a typical mid-May pattern for Cape Town, with daytime highs likely peaking near 19–21°C under variable Atlantic high pressure and light southerly winds. This range aligns with the market’s tight clustering around those outcomes, reflecting normal seasonal cooling after summer and the absence of strong warm-air advection or blocking ridges. Minor model spread arises from uncertainties in cloud cover timing and any weak frontal passage that could trim the afternoon maximum by 1–2°C. Historical May climatology shows average daily highs of 18–20°C at Cape Town International, providing a baseline against which today’s guidance shows little deviation. Updated runs tomorrow morning will refine the exact peak and determine whether the market resolves toward 20°C or 21°C.
