Current forecasts from agencies including the Met Office and Yr.no point to a daytime maximum of 16–17°C in Wellington on October 13, driven by a moderate northerly flow advecting milder air under mostly cloudy skies with light rain or drizzle periods that limit solar heating. Springtime climatology supports highs near 16°C as a baseline, though model runs show modest upside potential if breaks in cloud allow brief warming. Market-implied odds favor 18°C (52.5%) over 17°C (20.5%), reflecting trader assessment of forecast uncertainty and possible station-specific readings near the upper end of the range. Updated model guidance and official observations through the afternoon will determine the final recorded peak.
