**Trader consensus clusters tightly on 11–13°C for Wellington’s June 16 maximum, reflecting model agreement on a transitional synoptic pattern.** Recent northerly flow has kept early June temperatures above the ~13°C climatological average, with record warmth earlier in the month, but a front moving northeast across the North Island is expected to introduce cooler southerly winds by Tuesday, followed by a brief ridge and possible northwesterly shift. This setup favors modest daytime heating under variable cloud and scattered showers, limiting peaks compared with the preceding mild spell. Numerical guidance from MetService and other sources points to highs near 11–13°C, with rain timing and wind shifts creating the narrow spread between those bins; stronger or earlier southerlies could favor 11°C, while clearer intervals or delayed cooling could support 13°C. NIWA’s seasonal outlook for near-average conditions provides broader context, but short-term model runs and the next official briefing remain the key near-term catalysts before resolution based on MetService observations.
