MesoGauge Launching in South Carolina

Coming soon

Hyperlocal weather from the stations around you.

MesoGauge brings community weather stations, official observations, NOAA radar, satellite lightning and coastal buoys together into one live picture of the weather where you are, with an experimental nowcast for the hour ahead. Every number shows where it came from.

Every source, on one map

Most weather apps give you one number from an airport miles away. MesoGauge layers everything that is measured near you, and keeps each source visibly separate.

  • Community stations

    Home weather stations shared through the Citizen Weather Observer Program, delivered by NOAA MADIS.

  • MesoGauge contributors

    Stations connected directly to MesoGauge, shown at an exact spot, an approximate one, or kept private.

  • Official stations

    Airport weather stations from the National Weather Service and the FAA.

  • Radar

    NOAA MRMS precipitation rate, refreshed every two minutes, with an experimental nowcast for the next hour.

  • Lightning

    Lightning activity seen from space by the GOES-19 Geostationary Lightning Mapper.

  • Buoys and tide gauges

    NOAA buoys and water-level stations along the coast: wind over the water, waves, water temperature and the tide.

  • Forecasts and alerts

    National Weather Service forecasts, warnings and marine alerts, shown word for word.

How hyperlocal works

  1. Stations near you report

    Community, contributor and official stations report every few minutes, alongside radar and satellite lightning.

  2. Each reading is checked

    Readings are quality-checked. One that disagrees sharply with its neighbours, or a sensor that has stopped changing, is set aside, not averaged in.

  3. You get your place, with receipts

    Conditions for your exact place, and exactly which stations and sources went into them, one tap away.

What you'll find

  • Now

    Temperature, feels-like, wind, humidity and rain for your place, from the stations around you.

  • Map

    Radar, lightning and every station on one fast, private map. Forecast frames are always clearly marked.

  • Forecast

    The National Weather Service hourly and 7-day forecast in depth, plus an experimental next-hour rain nowcast.

  • Coast

    Water level beside the predicted tide, waves at the buoy, wind over the water and marine alerts.

  • Stations

    Every station's latest readings, where it is, and how its quality checks went.

Have a weather station?

MesoGauge is built around the stations in people's yards. Connect yours directly and choose whether it appears at its exact spot, an approximate one, or not at all. If it already reports to the Citizen Weather Observer Program, it will show up as a community station.

  • Works with common home stations
  • You control location precision
  • Private stations are never shown

Built to be trusted

Every number shows its source

See which stations and official products stand behind each value, how fresh they are, and what was left out.

Observed and predicted never blur

Observations, official forecasts and experimental predictions are labelled differently everywhere, from charts to map frames.

Honest about uncertainty

Experimental features are labelled experimental. Community data comes with its caveats, and a missing reading is shown as missing.

Public data, clearly credited

MesoGauge uses public data from the National Weather Service, NOAA MRMS radar, the GOES-19 Geostationary Lightning Mapper, NOAA’s National Data Buoy Center and tide stations (CO-OPS), NOAA MADIS (including the Citizen Weather Observer Program) and U.S. Census Bureau geography, alongside readings from contributors’ own stations.

MesoGauge is an independent project. It is not affiliated with or endorsed by NOAA or the National Weather Service, and it is not a warning system. Always follow official warnings.
