Wellington's peak September wind gusts depend on the intensity of pressure gradients driving airflow through Cook Strait, where topography between the Tararua and Marlborough ranges accelerates and gusts northerly or westerly flows. Spring climatology shows elevated storm frequency, with historical monthly maxima at Wellington Aero often ranging 100–140 km/h during strong events, though calmer periods can keep peaks below 90 km/h. Trader consensus remains balanced because long-range models show comparable odds for either typical spring patterns or an amplified system capable of exceeding 102 km/h, with key variables including the position of the subtropical jet and any early-season southerly outbreaks. Updated NIWA and MetService guidance closer to the month will refine these probabilities.

The resolution source for this market is the gust value in the wind group of NZWN's raw METAR/SPECI observations, encoded in knots (for example, "34020G45KT" denotes a 45-knot gust), as archived by the Iowa Environmental Mesonet (IEM) for station NZWN in network NF__ASOS ("New Zealand ASOS"). Gust speed is converted from knots using 1 kt = 1.852 km/h, rounded half-up to the nearest whole number. Because gusts are reported in whole knots, no observed gust converts to a value on a bracket boundary, so every observation maps to exactly one range.
The month's highest gust can be located via the IEM Data Calendar for NZWN: https://mesonet.agron.iastate.edu/sites/hist.phtml?network=NF__ASOS&year=2026&month=9&mode=monthly&station=NZWN. Each calendar day displays that day's peak gust inline; clicking a day's date opens the daily Summary for NF__ASOS, where the Peak Gust column in the NZWN (Wellington) row shows the day's maximum. Ensure station NZWN is selected, as the NF__ASOS network includes other New Zealand stations. Note that the IEM calendar and summary pages display gusts in mph; resolution is based on the knot value in the underlying raw METAR, which IEM archives alongside each parsed observation and which can be used to independently verify any value.
If any observations are missing or unavailable, this market will resolve to the range containing the highest gust reported during the resolution window. Should the IEM archive be unavailable or discontinued, this market will resolve based on the equivalent raw METAR/SPECI observations for NZWN from another credible archive or the original reporting authority.
