Recent meteorological data and forecast models from New Zealand's MetService point to a stable high of 13°C in Wellington on May 16, driven by typical autumn southerly flows and moderate cloud cover that limit daytime heating. This aligns with historical May averages for the capital, where maximum temperatures cluster around 12–14°C under similar pressure patterns. No significant warm advection or clear-sky radiative effects are expected to push readings higher, supporting the market's near-certain consensus. Traders are watching for any late-day shifts in wind direction or unexpected sunshine that could briefly elevate readings, though current model runs show low probability of such changes before the daily maximum is recorded.
