This market centers on the single highest air temperature recorded in Kuala Lumpur across the calendar day of 3 September 2026, the peak reading that defines how hot the Malaysian capital becomes over that one day. The daily maximum is a meaningful focal point because Kuala Lumpur's equatorial climate keeps afternoon highs within a narrow, humid band, so small shifts driven by cloud cover, monsoon activity, and rainfall timing determine whether the day tips warmer or cooler than a typical September. Traders are assessing the relative likelihood that the day's peak temperature lands at one whole-degree Celsius value rather than another, weighing recent observed highs, seasonal patterns, and short-range forecasts as the reading for the day is ultimately measured and confirmed.

1. Market Outcomes and Resolution Criteria: This submarket has exactly two outcomes — Yes and No. It resolves Yes if the highest air temperature recorded in Kuala Lumpur across the local calendar day of 3 September 2026, measured in whole degrees Celsius, is exactly 32°C, and No for any other value.

2. Definition of "Highest Temperature": The highest temperature is the single greatest reading in the temperature column across all reporting times for the observation day at the reference station, expressed in whole degrees Celsius as published by the resolution source. Standard station observations count; heat-index or "feels like" values, forecasts, and unofficial or crowd-sourced readings do not. Because the source reports whole degrees, a daily maximum of 31°C or 33°C resolves this submarket No, and only an exact 32°C resolves it Yes.

3. Official Sources and Evidence: The primary resolution source is the NOAA observation record for the Kuala Lumpur International Airport station (WMKK) at https://www.weather.gov/wrh/timeseries?site=wmkk, using the highest value in the temperature column for the observation day. The Weather Underground Daily Observations table for the WMKK station is used for corroboration and as a fallback if NOAA data is unavailable. The NOAA record is definitive in the event of any discrepancy.

4. Resolution Timing: The market is checked after the close of the observation day and resolves once the day's highest reading is confirmed, no sooner than 24 hours after the day's final observation is published on the resolution source. The local calendar day of 3 September 2026 concludes at 3 September 2026, 16:00 UTC, after which the 24-hour confirmation buffer applies; revisions posted before the first datapoint for the following date are incorporated, and all open positions are locked through to resolution.

5. Source Outages, Revisions, and Boundary Readings: If the primary source revises the day's readings before the first datapoint for the following date is published, the revised value governs; once the market has resolved, settlement stands. If NOAA data is unavailable, the Weather Underground Daily Observations table for WMKK is used; In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest

6. Ambiguities and Disputes: Where sources conflict, the NOAA record for the WMKK station takes precedence. Where a source's detailed per-observation record differs from any summary "day high/low" figure, the detailed temperature record governs. Any reading under active correction remains unresolved until the resolution source finalizes it.
