Recent short-range forecasts from Metservice, Met Office, and other models project a maximum of 12–13°C for Wellington on August 11, aligning with the tied 42.5% market-implied odds and the month’s climatological average high near 13°C. Primary drivers include southerly wind shifts expected to limit daytime warming, variable cloud cover, and the timing of any light showers or frontal passages that could suppress peaks by 1°C. NIWA’s seasonal outlook indicates near-average temperatures are most probable for the Wellington region through August, with limited model spread supporting the narrow 12–13°C focus over lower or higher outcomes. Updated model runs and local observations in the next 48 hours will refine the exact maximum before resolution.
