Forecast models from sources including the South African Weather Service and international guidance converge on a daytime high of 15–16 °C for Cape Town on June 15, consistent with typical mid-winter conditions under the influence of the cool Benguela Current and prevailing westerlies. Recent model runs show limited variability, with no strong warm advection or cold-front passage expected to push temperatures outside this narrow band. Historical June averages near 17 °C provide context, yet current steering patterns and surface pressure favor slightly cooler outcomes, underpinning the market’s heavy weighting toward 15 °C (31 %) and 16 °C (45 %). Updated guidance later today could refine these probabilities ahead of resolution.
