**Official MetService observations confirm Wellington's highest temperature reached 22°C on March 28, driving 100% market-implied odds on this outcome as traders align with verified data from the primary Kelburn station.** Calibrated thermometers at this long-term site recorded the peak amid mild autumn conditions, with partly sunny skies and moderate northerly winds supporting daytime heating consistent with seasonal norms (March averages around 20°C). Model forecasts from earlier in the week had clustered around 20–22°C, but final hourly readings solidified the result. Realistic challenges are minimal—only a rare post hoc data audit revealing sensor malfunction or a validated higher reading from Wellington Airport could prompt revision, though such occurrences are historically negligible for resolved daily maxima. No further updates expected.
