Recent meteorological observations and numerical weather prediction models from sources like the Met Office and GFS indicate a mild northerly airflow advecting warmer air over Wellington, supporting a daily maximum near 19°C on October 13 amid overcast skies and winds of 20–35 km/h. Current readings climbing through the mid-teens Celsius align with this consensus, consistent with typical spring variability where highs rarely deviate sharply without strong frontal passages. Trader positioning at 95.5% for 19°C reflects high confidence in these data, though minor uncertainties in localized heating or exact peak timing could allow a shift to 18°C or 20°C if observations revise. Official station maxima will finalize resolution.
