Wellington, New Zealand is widely recognized as the world's windiest city, and its airport regularly records powerful gusts that make headlines and viral landing videos worldwide.\n\nThe 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.\n\nThe 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.\n\nIf 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.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/what-will-be-the-peak-wind-gust-in-the-worlds-windiest-city-in-august-2026-17872-Pu3ru_tC-sHT.png","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/what-will-be-the-peak-wind-gust-in-the-worlds-windiest-city-in-august-2026-17872-Pu3ru_tC-sHT.png","active":true,"closed":false,"start_date":"2026-08-31T13:46:27Z","end_date":"2026-10-01T03:59:00Z","closed_time":null,"volume":80.618182,"volume_24hr":80.618182,"volume_24h_change":null,"normalized_vol_24hr":7.784150123596191,"normalized_volume":4.4085693359375,"liquidity":106.8404,"open_interest":41.018181999999996,"categories":["Climate and Weather"],"tags":[{"id":"84","slug":"weather","label":"Weather"},{"id":"102997","slug":"new-zealand","label":"New Zealand"},{"id":"103037","slug":"climate-science","label":"Climate & Science"},{"id":"104180","slug":"weather-science","label":"Weather & Science"}],"synthetic":false,"is_group":false,"group_key":null,"parent_event_id":null,"probability":null,"spread":null,"top_outcome":"89 km/h or below","top_outcome_probability":0.485,"top_outcome_prob_24h_change":-0.0050000000000000044,"top_outcome_volume_24h_change":39.618182,"updated_at":"2026-09-10T17:44:23.322858Z","fetched_at":"2026-09-10T17:44:23.322858Z","added_at":"2026-08-31T14:07:56.697140Z","url":"https://polymarket.com/event/peak-wind-gust-in-the-worlds-windiest-city-in-september","chart_24h":[0.0,0.0,0.0,0.0,0.0,20.0,39.818182,39.818182,39.818182,39.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,60.818182,80.618182,80.618182,80.618182,80.618182,80.618182,80.618182,80.618182,80.618182,80.618182,80.618182],"kind":"live","markets":[{"source":"polymarket","id":"4028555","event_id":"942003","slug":"will-the-peak-wind-gust-in-wellington-be-89-kmh-or-below-in-september-2026","question":"Will the peak wind gust in Wellington be 89 km/h or below in September?","group_item_title":"89 km/h or below","description":"This market will resolve to the wind-gust range that contains the maximum wind gust, in km/h, recorded in any routine (METAR) or special (SPECI) observation from Wellington Airport (ICAO: NZWN) between September 1, 2026 12:00 AM ET and September 30, 2026 11:59 PM ET.
