Recent ensemble forecasts from the South African Weather Service and global models indicate a moderating high-pressure ridge over the Western Cape following the May 11–12 cold front passage, supporting daily maximum temperatures near 21–22 °C on May 19. This outlook aligns with climatological May averages of 18–20 °C while reflecting residual cool maritime air advection from the Benguela Current. Model spreads arise mainly from uncertainty in afternoon boundary-layer mixing and localized sea-breeze timing, keeping the 21 °C and 22 °C outcomes nearly tied in trader sentiment. Updated guidance expected from the next model cycle will clarify whether slight warming or renewed onshore flow shifts the distribution.
