Tempest Weather System FAQs
Why do I want a weather station at my house?
Most weather apps and weather reports from your evening news are based on public domain data — primarily from weather stations installed long ago at regional airports. Having a reliable weather station at your home gives you the benefit of knowing the exact conditions outside, (not at the nearest airport). Tempest also provides hyper-local forecast info, customized to your location and can even help you save money on heating & air conditioning by allowing your smart home tech to make automated decisions based on real-time weather data. Want more info on the uses of a personal weather station? Check out this blog post.
How is Tempest's forecast better than others?
Improvements are made to the local forecast as the machine learning (AI) ingests observations from your weather station and other observations in your area. We pay a great deal of attention to the quality of the observations coming from your Tempest and our Continuous Learning AI seeks to improve the quality of your unique observations. You will notice advantages in accuracy over other forecasts starting about ~60 days from the time of installation. You may notice additional improvements going forward as we learn more about your local weather.
Can I see my Tempest data online?
Yes. Once your system is configured (using the Tempest Weather mobile app on iOS or Android), you can view data and forecasts from any browser at tempestwx.com. Log in to the website using the same credentials you used to create your Tempest account or view the station data as a guest user.
Do I need WiFi to use the Tempest Station?
It is highly recommended to connect the Hub to a WiFi network. Doing so will enable continuous uploading of weather data and allow anytime data access from anywhere.

Customer Reviews
Great Weather System! Has everything you need to track weather conditions. The Tempest Weather System also integrates with other devices too.
This is my second Tempest Weather System. The first Tempest Weather System failed. I didn’t quite get three years out of it. Weatherflow was able to offer a replacement at a discounted price. Hopefully this one lasts longer than the previous one.
I've owned the tempest for over 3 years now. To say I'm impressed is an understatement. I don't normally write reviews but I must say, I have only had 1 issues in over 3 years and that was a connection problem, all I did was unplug my base and plug it back in and everything was up and running perfect again lol. Knock on wood. Can't say I've had any other device that connects and communicates wirelessly on my property that is more reliable than my Tempest. I initially purchased it for the accuracy and no moving parts. I believe it was relatively new when I purchased in early 2021 so I purchased with the expectation of bugs, software glitches, and inconsistent connections. Beyond Impressed to say the least, I could go on and on but just know, I installed the tempest and haven't messed with it in 3 years other than resetting the base 1 time in those 3 years and and we have some pretty gnarly weather in Bama
I bought the Tempest system to take the place of my aging Davis system. After 20+ years of service, I am not willing to spend 3K to replace the one I have.
So, enter the Tempest system. Excellent, easy setup. WITHIN MINUTES.
After 24 hours of operation, I can happily report the Tempest System is within +/-2 degrees of temperature, within +/- 1-2 mph wind, within +/- 0.10 inHg of Barometer, and within +/- 3% of humidity FOR 7.5% of the PRICE OF A DAVIS SYSTEM.
I am impressed and looking forward to the first rainfall with this new system to see how close it comes to DAVIS and the standalone COCORAHS rain gauge I use daily.
If there were one feature of DAVIS I would request of TEMPEST? It would be the ability to upload information to other websites such as AWEKAS, CWOP, WEATHERCLOUD, etc. For the time being since the DAVIS is still operational, this is not a showstopper.
THANKS FOR A GREAT SYSTEM!
After seeing a Tempest in two nearby yards, I invested in this technology in order to more clearly understand local weather. So far, the Tempest station is exceeding expectations (and provides comparable data to the other two neighbouring Tempest units).
I learned from one neighbour that the Tempest will likely need a power boost during the rainy/snowy season here on the “Sunshine Coast” (north of the 49th parallel). That accessory should be bundled with the unit for northern locations.
Since forest fire smoke is a potential hazard here on the coast, I hope that additional data channels (PM 2.5, PM 10 etc) can be added to the Tempest station so that this excellent weather station can include air quality parameters.
Just received the package, nicely packaged, All in good shape 👌. Just set it up and seems to work great 👍
