Wellington, New Zealand, experiences peak September wind gusts shaped by its exposure to the Roaring Forties via the narrow Cook Strait, where westerly flows accelerate and become turbulent amid spring's shifting pressure patterns. Climatological records show monthly maxima commonly falling in the 90–101 km/h band during this windiest season, driven by frequent northerly or southerly events without extreme synoptic setups. A strong 2026 El Niño has likely reinforced westerly tendencies, supporting the market's 73% implied probability for that range while keeping the chance of 102 km/h+ gusts near 26.5% absent major storms. Official monitoring indicates no recent outliers exceeding typical spring thresholds, aligning trader consensus with historical baselines and remaining forecast windows.

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.
