MetService's latest forecast models for Wellington on March 28 project a maximum temperature of around 20–21°C, aligning with trader consensus where 21°C leads at 42.5% implied probability and 20°C follows at 32.5%, driven by persistent southerly winds ushering cooler maritime air after recent unsettled conditions. Observational data from the past 48 hours shows highs in the high teens amid cloudy skies and showers, with ensemble model guidance from NIWA and international sources converging on limited daytime heating due to high cloud cover and moderate northwesterlies developing later. Historical March averages hover near 20°C, but current sea surface temperatures slightly below normal temper upside potential; traders await this afternoon's updated 12Z model runs for any intensification signals, as small shifts in cloud or wind could tip outcomes.
