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.)
May 26, 2026
NewAdded a feature to the Map which allows you to click a station, and within the menu that comes up, you can add the stations temp observations to your model chart.
Dec 29, 2025
Bug FixFixed a bug with the "Wethr Flow" wind speed that was causing it to show inflated speed values.
Dec 27, 2025

Dec 22, 2025
UpgradeThe main dashboard and the multi-view dashboard both have streaming observations now, improving the update speed.
Dec 15, 2025

Dec 8, 2025
NewAdded Low temperature indicators for both resolution sources.
Bug FixFixed a bug that was allowing hourly and special metars to overwrite the most recent observation for the map even when newer observations were present.
UpgradeClicking on an observation on the main temperature chart will now automatically scroll the recent observations box to that observation.
UpgradeLow temperature functionality and some cosmetic enhancements were added to the multi-market dashboard.
NewWind flow is now visible on the map (updated every 15 minutes).

NewAdded KHOU, KSEA, KSFO and KDFW high temperature markets.
Nov 22, 2025
Bug FixFixed a bug that prevented current day total rainfall from showing on the precipitation dashboard for KNYC.
Nov 20, 2025
NewA beta release of the Precipitation Market Dashboard is now live.
Nov 18, 2025
UpgradeTwo new modes have been added to the API. Wethr High mode provides the current Wethr high. Latest Observation mode lets you pull the most recent observation only.
Nov 15, 2025
UpgradeUpgraded Temperature Models chart to true time series with zoom/pan capability.
UpgradeAdded the ability to view observations on the Temperature Models chart in "decimal" form.
Nov 14, 2025
Bug FixFixed a bug where non-precise 5 minute observations could overwrite the temperature of hourly/speci observations, causing the hourly/speci to be recorded and displayed incorrectly.
Oct 29, 2025
UpgradeAdded a dewpoint column to the "Recent Observations" display area.
UpgradeAdded a dewpoint column to the "Recent Observations" display area.
Oct 28, 2025
NewAdded all forecasts except for NWS to the Wethr.net API (available to Pro users).
Oct 21, 2025
Bug FixFixed a bug that was allowing the first 6 hour high of the day to be included in the Wethr High calculation even if it extended into the previous day.
Oct 20, 2025
Bug FixChanged the rounding formula for Polymarket Stations (EGLC, KLGA) to match the rounding used by Weather Underground.
Oct 12, 2025
NewThe following data points have been added to the API and the documentation has been updated: Heat Index, Relative Humidity, Visibility, Altimeter, Sea Level Pressure, Pressure Tendency, Precipitation, 3 Hour Precipitation, 6 Hour Precipitation, 24 Hour Precipitation and Snow
UpgradeMade it so that Obs Min and Obs Max (Observed Minimum and Observed Maximum) hide/show preferences on the Temperature Models are remembered.
Bug FixFixed a bug that caused the "time since last update" for stations on the map to show up as "Invalid time". (Thank you mrage!!!)
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
UpgradeThe main temperature chart has been upgraded to a time series chart, which will make the spacing between observations based on the time between them instead of all points being equally spaced.

Sep 29, 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

Jul 31, 2025
