MetService's latest evening update on April 11 forecasts a high of 19°C for Wellington on April 13, with a few morning showers and strong westerlies turning northerly, anchoring trader consensus around 18–20°C at 27–28.5% implied probabilities each. This tight clustering reflects model agreement on a mild frontal passage, where northerly advection could boost afternoon peaks toward 20°C if showers clear early, versus persistent low cloud and rain capping at 18°C. Winds nearing gale force add variability in mixing cooler marine air, while April climatology averages 17°C highlight the setup's warmth potential. Sunday morning's forecast refresh from MetService and NIWA will likely sharpen resolution as the event nears.
