**Trader sentiment for the highest temperature in Wellington on July 1, 2026, centers on 12°C as the clear leader (47% implied probability), followed by 11°C (24%), reflecting short-term forecast consensus and climatological norms for early winter.** Current MetService guidance indicates partly cloudy conditions with light winds on July 1, supporting a daytime maximum near 12°C and overnight low around 4°C. This aligns with Wellington’s July average high of approximately 12°C (53–54°F), where daily maxima typically range 11–13°C. NIWA’s May–July seasonal outlook assigns roughly equal chances of near-average or below-average temperatures for the Wellington region, bolstered by the emerging El Niño pattern favoring west–southwest winds and cooler anomalies. AccuWeather’s extended July outlook similarly projects daily highs between 10.5–14°C, with the most probable values clustered around the long-term mean. No significant model shifts or atmospheric developments have emerged in recent days to favor warmer or colder outliers, keeping the market-implied odds anchored to the 11–13°C band while the tight timing to resolution limits upside for extremes.
