MetService's latest forecast, issued late Thursday, projects a 13°C high for Wellington on May 17 under mainly fine skies with southeasterlies and a chance of afternoon showers, anchoring trader sentiment with 13°C and 14°C as co-favorites in the closely contested market. Persistent cool southerly airflow from recent frontal passages, combined with a stabilizing high-pressure ridge over the South Island, caps daytime heating, while Wellington's coastal exposure to Cook Strait winds adds variability—light winds could allow brief sea breeze warming to 14-15°C, but cloudier pockets or gusts may suppress peaks to 12°C. NIWA seasonal outlooks align with near-average May highs around 14°C, but short-range model ensembles reflect 1-2°C uncertainty ahead of Saturday's update.
