Recent MetService guidance and numerical weather prediction models indicate a daytime maximum near 14°C for Wellington on May 18 under persistent southeasterly flow and variable cloud cover, positioning that outcome as the clear leader in trader sentiment. Mid-May climatology for the region shows average highs clustered tightly between 12°C and 15°C, with Cook Strait moderation limiting extremes; current guidance aligns closely with these historical baselines rather than signaling a warmer northerly regime or cooler post-frontal surge. Ensemble spread remains modest at this 48-hour horizon, though minor shifts in wind direction or cloud timing could still nudge the peak into the adjacent 13°C or 15°C bands. Updated model runs and official briefings in the next 24 hours represent the primary near-term catalysts for any repricing.
