Recent passage of a cut-off low and associated cold front over the Western Cape has advected cooler maritime air, positioning Cape Town’s June 5 maximum near the long-term seasonal average of 17°C. Numerical weather models show consensus on daytime highs of 16–18°C under continued onshore flow and limited solar heating, consistent with the market’s heavy weighting toward those outcomes. Historical records indicate early-June maxima rarely surpass 20°C without a strong subtropical ridge, while recent cooling has further reduced upside potential.
