This app requires the Tempest sensor device, which is available to buy separately.
Need to set up and configure your Tempest Weather System? The Tempest app will walk you through a few simple steps, including connecting your home’s WiFi network. Once you’re up and running the app will quickly become your go-to for real-time weather conditions, lightning and rain alerts, and the most accurate forecast for your location - guaranteed.
Data available in the Tempest app includes:
Temp, humidity, dew point, feels like, heat index
Barometric pressure, sea-level pressure, trends
Lightning detection and alerts up to 40 km
Wind, UV, solar irradiance
Rain rate, accumulation, rain onset alerts
Historical weather data graphs
Smart Home Ready:
Use this app to save time, energy, and water by integrating with popular smart home and irrigation services. Use your weather data to optimize heating and cooling, adjust your irrigation schedule, and alert your family when lightning storms approach. Tempest is compatible with Google Assistant, Rachio, IFTTT, Siri, Alexa, Homey, and many more.
Weather Geek Worthy:
The Tempest device features an all-in-one sensor and long-range wireless connectivity (1000ft), sonic anemometer, and haptic rain sensor, but it is far more than just a cutting-edge piece of hardware. Each Tempest leverages WeatherFlow-Tempest’s patented Nearcast Technology™, which feeds real-time observed weather data from your backyard into a machine learning system to dramatically improve forecast accuracy where it matters most.
Tempest’s open API and shareable data enable third-party use, with built-in publication to desktop software and online services.

Ratings and Reviews
Lacks Map, Cannot display more than one station
I changed from a Davis station to a Tempest. Overall I think the station is very good, but it has a couple of annoying nits. First, when mounting, it can only accommodate a 1” diameter pole. Needs to have a wider adapter. Also, the solid state rain sensor is so-so. In the Northwest, we have lighter rain. It’s not so great with lighter rain. The company can disable the software filter for you, which can improve accuracy.
WRT the software, it’s a comprehensive piece of software that also shows the local forecast. I knocked one star because of two significant deficiencies: (1) there is no map that shows you the location of your station compared to other stations and that would show conditions at surrounding stations (note that their website has such a map, so integrating it into the software should be easy) and (2) if you don’t own a station, you can’t use the software. One should be able to have the software pull information from any station, even if you don’t own that station. I suspect they think this arrangement will sell more stations, but I think the opposite would help sell stations. If they allowed anyone to install the software and link to any station, they would encourage more people to buy the stations after they realize how cool the software is.
A good piece of software with accompanying good hardware. Just a couple of minor issues.
Developer Response ,
Hi Cyclist Edge, great feedback!
1. The pole mount does accommodate a standard 1.25 inch antenna mount or any one-inch nominal pole or pipe (1.315 inch outer diameter) and anything in between.
2. We hear you loud and clear on the tempest map (https://tempestwx.com/map) suggestions.
3. Also great feedback on the app being for hardware owner's only. WeatherFlow has other weather apps that might be better suited for this kind of user - and those apps have public Tempest station data available too!
Clever device but UI has accessibility issues
First, understand that Tempest Weather Station is a device for collecting local surface meteorological observations for use by Weather Flow. It does this reasonabley well. It is very good at thermodynamics properties measurement. It is less good at wind speed and rainfaill.
WeatherFlow collects the data and provides it to weather services for use in model initialization. In return, it provides a local forecast for your location with more precise time of arrival information than that in NWS official area forecasts. This helps with planning outdoor activities.
The Tempest Weather app lets you see the current conditions and forecast on the go. I'm post-cataract surgery but still have near focus deficits. I have trouble reading the percipitation probability values in the iPadOS version of the app. The iPhone version is more readable.
The temperatures above them are easily read. WeatherFlow needs to review the UI for readability. If Gramms can't read it, it needs work.
WeatherFlow offers a number of activity specific Apps for sailing, kite surfing, agricultural operations, etc that use the WeatherFlow refined local data and modeling. These are subscription services. They may not require a local weather station. These are an example of what WeatherFlow can do with its refined local data and modeling.
Best Comprehensive Weather Station Available
This brilliantly-designed, sturdy, compact, wireless weather station using sonic, haptic, and computer technology provides not only instantaneous but also historical data of all meteorological parameters. Particularly noteworthy is the Tempest’s comparative data access to multiple other local/regional Tempest stations coupled with experiential learning and AI to produce truly local (“micro”) and regional (“macro”) forecasting that always equals or beats the NWS. The personal Tempest webpage that comes with the station is accessible by cell phone or computer anywhere in the world with Internet as well as to multiple family members. Moreover, at an individual owner’s discretion the data can be shared with The Weather Underground’s network!!
I live right on the North Atlantic coastline and have been fascinated by its ever-changing weather conditions, for decades using analog wireless instruments: namely Maximum’s Criterion Maestro Anemometer/Mini-Max Temperature together with a Chelsea Professional Shipstrike aneroid barometer augmented by internet data out of Pease International Airport’s tower. I find my new Tempest unit tracks all this data precisely, but gives far more meteorological information AND historical trending.
Perhaps the most amazing aspect of the Weatherflow Tempest is just how easy it is to get it set up and running!!
