**Recent observational data from Wellington-area weather stations, including peaks reaching 19°C during the afternoon under a stable high-pressure regime with light easterly flow, has driven the market-implied odds overwhelmingly toward that outcome.** Official monitoring shows maximum temperatures aligning precisely with this threshold amid mostly cloudy skies and minimal precipitation, consistent with spring climatology for the region where October highs average near 16–18°C. Model consensus from sources like the MetService and international ensembles supported limited afternoon warming without significant advection of warmer air masses. While minor station-to-station variations or post-event quality control could theoretically adjust the recorded high, the tight clustering of real-time measurements makes substantial revision improbable before resolution.
