MetService's latest April 3 afternoon update forecasts a 19°C high for Wellington on April 5 amid partly cloudy skies, northerlies turning southeasterly, and a chance of afternoon showers, closely matching trader-implied odds favoring 18°C (32.5%) and 19°C (28%). Persistent northerly winds, drawing warmer air from the north, support these mild autumn temperatures above the April climatological average of 17°C, with recent days logging highs near 19-20°C. Key differentiators include shower development and cloud cover timing—earlier onshore flow could cap peaks at 18°C via reduced solar insolation, while delays enable 19°C—reflecting typical 48-hour forecast uncertainty in ensemble models. Watch for MetService's April 4 morning revision.
