**Wellington's July winter climatology centers daily maxima around 12–13°C, with 14°C emerging as the modal outcome in recent model guidance.** Short-range forecasts from sources like the Met Office and AccuWeather project a July 23 high near 13°C under typical southerly flow and moderate wind, while seasonal NIWA outlooks indicate near-average or slightly below-average temperatures for the Wellington region. Trader consensus at 51.5% on 14°C and 21.5% on 15°C reflects the narrow uncertainty band in ensemble runs and the potential for brief diurnal warming or measurement timing effects at official stations. Lower probabilities cluster around 12–13°C as the most likely baseline given persistent cool air masses, with tails below 11°C or above 16°C discounted by current steering patterns and lack of strong high-pressure blocking. Updated model runs and any MetService briefings over the next 48 hours will be the key catalysts shifting implied probabilities.
