This market centers on the highest air temperature recorded in Kuala Lumpur on 16 September 2026, framing the day's peak reading as an outcome to be sorted into a set of whole-degree Celsius brackets. Kuala Lumpur's equatorial climate keeps daily maximums within a narrow and closely watched band, which makes a single day's high a precise and meaningful focal point for gauging short-term weather variation across the region. Traders are assessing how likely the day's peak temperature is to land on each candidate value, weighing seasonal norms, recent station readings, and forecast guidance against the official temperature observation that will ultimately record the day's high.

1. Market Outcomes and Resolution Criteria: This market resolves YES if the highest temperature recorded at Kuala Lumpur International Airport (station WMKK) on the local calendar day of 16 September 2026 is 35°C, and resolves NO if the recorded high is any other whole-degree value. A Tie resolution applies only under the conditions in Rule 5, in which case all positions settle at $0.50 per share.

2. Definition of "Highest Temperature": The highest temperature figure, in whole degrees Celsius, listed for the Kuala Lumpur International Airport station (WMKK) over the Kuala Lumpur local calendar day (Malaysia Time, UTC+8) of 16 September 2026. Temperatures are recorded to whole degrees Celsius by the resolution source and that reported whole-degree figure is used directly; forecasts, "feels-like" values, and readings from any other station do not qualify.

3. Official Sources and Evidence: The primary source is NOAA (National Oceanic and Atmospheric Administration) daily observation data for the Kuala Lumpur International Airport station (WMKK) at https://www.weather.gov/wrh/timeseries?site=wmkk — the highest value shown in the observation "Temp" column. If NOAA data is unavailable, the Weather Underground Daily Observations table (wunderground.com) for the same WMKK station is used. The NOAA record is definitive in the event of any discrepancy.

4. Resolution Timing: The market is evaluated once the full daily observations for 16 September 2026 are published, and resolves no sooner than 24 hours after that daily observation is posted on the primary source. All positions remain locked through to resolution.

5. Data Availability and Corrections: This market has no scheduled event to postpone; it settles on recorded observations. If the primary source is unavailable, the fallback source in Rule 3 applies. If the source revises or restates the day's reading before resolution, the corrected figure is used; once the market has resolved, settlement stands. If neither source provides an eligible reading and the outcome remains genuinely ambiguous after a 24-hour waiting period, the market resolves Tie with all positions settling at $0.50 per share.

6. Ambiguities and Disputes: Where readings conflict, the NOAA record for the WMKK station takes precedence, followed by the Weather Underground Daily Observations table for the same station. Only observed readings for station WMKK count; estimates, forecasts, and observations from other Kuala Lumpur locations are disregarded. All times in these rules are expressed in UTC unless a local calendar day is specified.
