Official forecasts from New Zealand's MetService currently project a daytime maximum of 16°C in Wellington on May 22, driven by moderate northerly flows and limited cloud cover that support modest warming under typical late-autumn radiative conditions. This aligns with the market-implied 47.5% probability for 16°C as the leading outcome, while 15°C and 17°C options reflect minor model spreads in boundary-layer mixing and wind strength. Wellington's May climatology shows average highs near 14–15°C, so any deviation hinges on short-term synoptic shifts; resolution will draw from official observations at the Kelburn station, with traders closely monitoring the final 24-hour model runs for potential adjustments to these probabilities.
