An AI-Powered Weather App With Guaranteed Accuracy

While general weather apps abound, the Tempest app is different. It feeds real-time observed weather data from your backyard into a machine learning system to dramatically improve forecast accuracy where it matters most – your home. No other weather app or forecast can compare because they don’t start with the weather conditions at your specific location.

Tempest Weather Station Reviews

“This truly is the only ‘rain sensor’ that has ever really worked consistently with my smart irrigation controller, and I get all the other great weather station features as well.

“I have owned many weather stations but hands down, this has to be the best I have had. As advertised on your quick guide, I was up and running in 5 minutes once I opened it out of the box.”

“Tempest is very accurate compared to actual weather as monitored by other stations nearby. It gives plenty of data and best of all, stores this and is accessible via the app.”

“I would suggest that everyone who owns or operates a business should purchase one of these to ensure you get a proper payout from your insurance company.”

“I bought my Tempest to replace an Acurite Atlas. I was constantly having to fiddle with our Atlas. The Tempest has been a breeze. Great App. Great Support. Highly Recommend.”

“Temperatures have been spot on, wind readings are responsive and accurate. The lighting detection is unbelievable – you can track storms heading in and leaving with just this feature alone. Highly recommend the new Tempest.”

“Set up was a breeze. My Tempest was up and running in less than 10 minutes, and that included an email exchange with their support team to help me troubleshoot an issue that turned out to be operator error!”

“It’s amazing how it tracks and charts rain intensity, accumulation, lightning activity and wind speed/direction, along with many other parameters. It’s truly an incredible PWS!”

“To have this much power in one self sufficient unit is a dream come true. Plus, the neighbors all love the way it looks on the fence.”

Nearcast Technology™ for an accurate forecast

What makes your Tempest forecast so accurate? It starts with your weather data. In addition to your Tempest observations, we ingest a massive amount of data from satellites, radars, government surface networks, etc. Initialized with our curated data sets, we also run our own high-resolution numerical weather forecast models. We train our AI-based output models to produce accurate point-specific forecasts informed by the observations. The result is a forecast tailored to your exact location.

All About the Data

Accurate measurements from your location, along with data from other Tempest Systems, flows to our Nearcast data processing and quality control system. There we also collect and curate ALL other relevant weather data, including measurements from satellites, aircraft, radars and other surface weather stations. Our Nearcast data process ultimately yields standardized data and a real-time analysis product. Not every measurement is of equal value (e.g. wind ‘shadows’ affect how wind data is utilized) but our big data analytics adjust accordingly, meaning every Tempest System can make a difference.

Help Create a Better Global Forecast with the Tempest Home Weather Station

Tempest data, along with all our real-time useful information, is part of data sets which are shared with the National Weather Service (NWS-NOAA) and other met agencies across the world, supporting their mission of predicting dangerous weather and warning the public of potential risks. As forecasting becomes more difficult and weather patterns increasingly erratic, each Tempest system helps contribute to a better global forecast.
