NewAdded support for the Kalshi Hourly "Index" markets.
https://wethr.net/hourly-index
Sep 4, 2026
Bug FixDeployed a bug fix that catches re-broadcasts of hourly metars that appear to be special metars due to incorrect header times, but are clearly duplicates of the previous hourly metar. These were capable of causing incorrect temperature and precipitation values from the last hour of yesterday to be assigned to today.
Sep 3, 2026
UpgradeAdded the option to show wind in degrees in the recent observations table.
Bug FixFixed a display bug on excluded observation rows in the recent observations table when switching between Weather.com and Weather.gov resolution.
Sep 2, 2026
UpgradeAdded some UI enhancements for Weather.gov logic to explain some of the nuances.
UpgradeAlerts set using the temperature chart bell icon are now fired in real-time as opposed to at 1 minute intervals. The expiration has also been changed from 72 hours to "end of market day"
Aug 31, 2026
NewRolled out Weather.gov logic for the new Polymarket.com resolution, active on 48 of Polymarket's temperature markets. The new logic is available on all dashboards and APIs.

Aug 1, 2026
Bug FixFixed a bug that caused buoy times to show up as UTC instead of their correct timezone.
Bug FixFixed a bug in an ingestion script that allowed data from a future date to get into the database, causing the PUSH API and REST API's "latest" functionality to get stuck looping an observation from a future date.
Jul 28, 2026
UpgradeThe dashboards have all been upgraded to support the "pending" observations that come through with the new faster hourly data when in IBKR/Poly/RH
You will see a dashed line for pending data and it will not be reflected in the Wethr High/Low in Poly/IBKR/RH resolution mode until a second source has confirmed it.
Additionally, you will see a "pending" value in the Wethr Extremes area of the dashboard and in the recent observations it will be notated as "mt-p" for pending metar.
A pending metar may remain pending for the entirety of the day if it is never picked up by a second source. In that case, it will remain on the dashboard until a higher/lower (depending on which extreme we're talking about) confirmed metar is achieved.
Note: The data is real - it is simply a matter of "will WUnderground pick it up" - and requiring a second source closer to their ingestion path will dramatically reduce the rate of error.

UpgradeBoth the REST and PUSH API for observations have been updated to include new fields which are of the most importance for WU highs and lows.
Over the last few days one of our new data sources has reliably provided hourly/special metar data that traditional metar sources fail to obtain during outages between the FAA and NWS. As a result the Wethr high/low in WU mode could differ from the resolution source if data came through to Wethr during one of those outages.
To protect users from this and give them full autonomy on using or disregarding this much faster data based on their own risk tolerance, we have excluded this faster source from the Wethr High/Low for WU resolution mode until a second source confirms it, however we make the "potential" new high/low data available during that window.
API documentation for the new fields can be found at:
REST: https://wethr.net/edu/api-docs#v2-obs-preliminary
PUSH: https://wethr.net/edu/api-docs#v2-push-preliminary

Jul 18, 2026
NewAdded Relative Humidity and Altimeter columns (optional, off by default) to the Recent Observations table.
UpgradeUpdate to the Map (both standalone and in-dashboard) that both reduces required bandwidth and improves station update speed. This update further reduces station update latency on the map by up to 1 minute. Looking at further tweaks that could reduce it even further.
NewIt appears that our PWS efforts have yielded a substantial number of new stations now showing on the map. This was an unintended bonus.
UpgradeHuge improvement to personal weather station latency was just pushed live. For many personal weather stations we are seeing a 10 minute improvement. This is a global improvement. Not all stations on the map are impacted by this, but thousands are.
Jul 17, 2026
UpgradeUI upgrades to the legacy dashboard "Recent Observations" section. Aligned it more with the widget dashboard version, which is nicer on mobile.
UpgradeAPI Improvements (Source Attribution): Wethr High/Low responses and Push events now include which sources (metar, hf_metar, omo, 6-hour, dsm, cli) have confirmed the current high/low, with per-source counts and first-confirmed times. Additive; no breaking changes. Docs: REST · Push
NewThe 48 hour version of HRRR has been added as model HRRR-EXT and the API documentation has been updated to reflect the addition.
Jul 16, 2026
NewAdded "crossover" data to the recent observations chart to show what temperature was crossed over in the ASOS station between observations (and in which direction) in order to change the base Celsius value.
NewAdded a "temperature blind spot" indicator option to the main temperature chart, accessible through the chart settings. This highlights temperature rows on the chart that cannot be confirmed by non-precise observations (HF-METAR, OMO) without moving beyond the current temperature (or range).
Jul 1, 2026
UpgradeRemoved the "New Dashboard Available" banner on the legacy/original dashboard and replaced it with a permanent link to the "Widget Dashboard". (only visible for non-free users)
NewMade the High/Low Notifier Tool use the user default dashboard settings for its dashboard linking purposes.
UpgradeAdded the ability to set your dashboard preference, which will control where the header navigation takes you (Legacy or Widget Dashboard)
Jun 29, 2026
Bug FixFixed a bug that was causing Relative Humidity to show up incorrectly on the temperature chart (but correctly on the model chart) for Metric/Non-US stations.
Jun 23, 2026
RollbackRemoved the 10m observations from EDDM because they are not coming from the exact same senor that provides the METARs used for resolution. Instead - these 10m observations have been added as a neighbor station (EDM-DWD), which will allow you to add it to your model chart if desired.
UpgradeModified all model charts (both dashboards and the model viewer) so that when hovering over a line or legend item, all other lines are dimmed.
Jun 22, 2026
Bug FixHardened METAR ingestion to prevent 6-hour high/low collision. A broken KLAS metar that was missing KT in the wind section prompted this improvement.
Bug FixUpdated the front-end dashboards and all API endpoints to provide the correct Wethr High/Low for international stations using Weather.gov for resolution regardless of which resolution mode is selected. The impacted stations are UUWW, LTFM, LLBG
Jun 19, 2026
NewReleased the Solar and Thermal Cycle module for Pro + dashboard users.
Jun 17, 2026
UpgradeAdded additional data quality flags to observation API outputs. The API now checks for a wider range of data quality issues.

Jun 9, 2026
UpgradeImplemented latency improvements for French stations.
Bug FixFixed France observation ingestion which broke due to recent changes from the upstream provider.
Jun 4, 2026
UpgradeReleased a data quality enhancement to both PUSH and REST observations APIs. The new data quality flags are designed to help minimize the risks associated with sensors that are malfunctioning. Full details here: https://wethr.net/edu/api-docs#v2-obs-data-quality
Jun 1, 2026
Bug FixFixed a bug on the API section of the Account page that was still showing the old API limit for Developer plans. This was a cosmetic bug only and has been fixed to reflect the new 100,000 daily request limit for Developer plans.
UpgradeMade some alterations to the Similar Days Tool (v9) to make the observation data have proper time series alignment. (This does not change the predictive functionality, which is still tied to hourly intervals)
May 29, 2026
UpgradeForecasts API expanded with 17 new fields (humidity, dew point, apparent temp, wind, cloud cover, precipitation, weather code, pressure). Additive and backwards compatible; nullable where a model doesn't supply the variable.
NewWe have released a REST API for model pacing which provides the same pacing data that you see on the Wethr.net dashboard.
Bug FixThe GEM-GDPS model underwent some upgrades, which caused a break in our ingestion flow. This has been resolved and fresh model data should begin flowing with the next ingestion cycle.
UpgradeThe Daily request limit for Developer plans has been doubled from 50,000 to 100,000 effective immediately.
May 27, 2026
UpgradeImproved the Preferences UI in the Account section to allow for easier selection of desired markets. (This area controls the markets you see in the navigation bar.)

NewAdded a tool to convert the NWS time series chart temperatures to an actual Fahrenheit range, demystifying the rounding confusion.
Oct 11, 2025
Bug FixFixed a bug that prevented the time window buttons from working before a new update had arrived.
NewAdded an expandable details section at the top of each market that provides info about the location of the station and links to the associated futures market and resolution source.
UpgradeImproved main temperature chart scale by forcing it to scale dynamically based on what is visible on the chart. (before it was considering items that were hidden from view and also considering the full day of data resulting in "flatter" temperature lines, especially when using the time window buttons for 2/6/12 hours)
Oct 10, 2025
NewTime window buttons have been added to the main temperature chart to allow viewing only the most recent 2, 6 or 12 hours instead of the full day.
UpgradeThe map updates have been synchronized with the observation updates instead of running on its own update schedule (formerly 1 update per minute).
Bug FixFixed a bug that caused data to be loaded twice immediately upon loading the dashboard. This should make the initial page load smoother.
Oct 9, 2025

UpgradeImproved the Temperature Models chart to show all observations for clearer pacing.
Bug FixFixed a bug that prevented observations from showing on the Temperature Models chart for KNYC.
UpgradeAdded observations to the NWS Forecast Evolution Chart for the current day. (eg. 12pm on NWS chart will show the observation from 12pm, except in the case of KNYC, where it will show the 11:51am observation)
Aug 27, 2025
UpgradeAdded a lot of stations to the neighboring stations map.
UpgradeThe Neighboring Stations Map is now available to Pro users in full-screen at https://wethr.net/map
