Official meteorological observations confirm a maximum temperature of 20°C in Cape Town on June 1, driving the market's near-certain consensus on that outcome. This reading aligns with early-winter patterns in the Southern Hemisphere, where Cape Town typically sees daytime highs near 17°C amid cooler Atlantic influences and variable cloud cover. Ensemble models and station data from the South African Weather Service converged on this value without significant upward revisions, reinforcing trader confidence. While minor discrepancies in microclimate stations or post-event adjustments could theoretically alter resolution, the consistency of official reports across multiple sites leaves little realistic scope for deviation.
