| Rule | Kalshi | Polymarket |
|---|---|---|
| What counts as the high | The day's official high for the station, as The Weather Company publishes it for Kalshi (weather.com/kalshi) for events from Aug 14, 2026. It has matched the NWS climate report's official high on 1,587 of 1,588 settled days, and that high counts a peak between hourly reports. | The highest reading in the "Temp" column of NOAA's time-series page for the station, using its hourly data, in whole degrees. A peak between two readings isn't in that column, so it can come out lower than the official high. |
| The day | Midnight to midnight local standard time, so 1 AM to 1 AM while clocks are on daylight time. | Every time listed on that day on NOAA's page, which shows the station's local clock time. |
| The ranges | Two-degree brackets, with an open bracket at each end. Where the brackets start moves from day to day (61°–62° one day, 62°–63° another). | Two-degree ranges that start on an even number (62°–63°), with an open range at each end. |
| When it settles | After the final report for the day is out, usually the next morning. | Once the first reading of the next day is on NOAA's page, or by 11:59 PM Eastern the next day. If NOAA has no data by then, the Weather Underground daily observations table is used. |
