Current forecast models from South African and international agencies point to a maximum temperature of 20–22°C in Cape Town on May 18, driven by the moderating influence of the cold Benguela Current and typical autumn conditions in the region’s Mediterranean climate. Recent observations show daytime highs near 19–20°C with light southeasterly winds and limited cloud cover, keeping values within historical May averages of 18–21°C. The near-even market odds between 21°C and 22°C reflect lingering uncertainty over whether a brief northerly flow or clearer skies could push the peak slightly higher, while the sharp drop in probability below 20°C or above 23°C aligns with low likelihood of significant cold-front passage or anomalous warming in the next 48 hours.
