MetService's latest forecast pins Wellington's highest temperature on March 24 at 21°C, with fine spells and light winds, driving near-unanimous trader consensus at 100% implied probability. Ensemble models from ECMWF and GFS align closely, showing daytime highs stabilizing around 21°C amid a cool southerly flow and post-frontal clearing, consistent with March climatology where averages hover 19-22°C but rarely exceed 23°C this late in summer. Historical data supports this, as only 5% of similar setups have busted higher. Challenges could arise from an unforeseen northerly wind shift injecting warmer air, though low-pressure dominance makes this improbable per current upper-air analyses. Traders eye tomorrow's 1200 UTC update for confirmation.
