Trader consensus around a 13°C low for Wellington on October 13 reflects consistent observational data and model runs showing overnight temperatures stabilizing near that threshold under persistent cloud cover, northerly winds, and mild maritime air. Official forecasts from sources like MetService and global models indicate minimal radiative cooling overnight, with readings holding between 13–14°C amid high humidity and wind speeds that limit temperature drops. This aligns with typical early-spring climatology for the region, where such conditions suppress extremes. A rapid clearing of skies or an unexpected southerly wind shift could allow brief further cooling, though current model consensus and late-day observations make significant deviation unlikely before resolution.
