Windy Launches Premium 15-Day Forecast for ECMWF Model using AIFS technology
-
We're excited to unveil our latest feature: ECMWF (European Centre for Medium-Range Weather Forecasts) has developed its own data-driven forecast model called the Artificial Intelligence/Integrated Forecasting System (AIFS)!
-
Extended Forecast: Get a detailed weather outlook for the next 15 days, helping you plan your activities and trips with greater accuracy. Simply go to the detailed forecast of any location with the ECMWF model.
-
Global Coverage: Access precise weather forecasts for any location in the world. Whether you're checking the weather for your hometown or the destination of your next trip, Windy.com has you covered.
-
Detailed Insights: Our 15-day forecast provides in-depth information, including temperature trends, precipitation probabilities, wind speeds, and more.
However, looking 15 days ahead into the weather is risky. This is why we recommend using this long forecast as a trend-watching tool rather than planning your activities for specific days based on this forecast solely.
🤖 How does AIFS work?
These systems use advanced machine learning models to analyze current and past weather patterns, providing accurate and detailed forecasts. AIFS employs ensemble forecasting for reliability, continuously learns and updates its models, and delivers real-time updates. The result is increased forecast accuracy, early warnings for severe weather, personalized predictions, and improved decision-making across various sectors, significantly enhancing our ability to respond to weather changes.

@Polina-Nozdrina Why is the AIFS model limited to only ~7+ days out?
-
@stephenm00
AIFS forecast is displayed in Windy as an extension (+ 5 days) of IFS, the ECMWF model used by Windy.
AIFS has a 0.25° resolution while the one of IFS is 0.1° (9km). So I guess there is no real advantage for using AIFS for the first 10 days. -
Good day.
Love Windy and it's my go-to for long range forecasts. I live on a small island in the Caribbean and it's especially important to know what's coming at us.
The new 15 day forecast is great. Thank you -
Dear Windy,
I am a premium member, but the ECMWF forecast is still only 10 days on my phone app.
How can I access the 15 day version?
Regards,

Thanks windy … Happy to get this new feature but 15 days AIFS not showing on both iPhone and iPad

Seems the 15 days forecast is not showing on the bottom ruler hence you need to pick a specific location to get the AIFS 15 days. Would be nice to get also the 15 days on the opening screen to get a general overview of a larger area/region. I’m sailing and this would help to assess and take decision on the next passage.
Thanks Windy Team -
Thanks Gavin,
-
@idefix37 Thanks but still … would be ‘a nice have’
-
AIFS extension to the standard 10 days is displayed in the point forecast table.
Here shown in iPhone in landscape mode

@Polina-Nozdrina Ever since I subscribed to windy, 4 years ago, I've been enjoying it at work. Most of the time it shows correct reports. Keep it up, we need Have fun dear.
-
15 days ahead plus minus all possibilities we have, that is great to think about specifically to learn a lot about Life on Earth, thank you all ! And by the way the artificial intelligence for support in it.
-
@Polina-Nozdrina Thanks for this nice new feature :)
However it seems that my phone is not wide enough as the days are not displayed in the top chart which makes it a bit useless. They do appear when I switch to landscape view though. I guess you are aware of this UI issue.

@Polina-Nozdrina
I can't make the payment smoothly. I've never used such a crappy payment system. -
@Victor_windy Hello, could you please provide more info about your device?
-
@浙江省应急 HI, I see you were successful at the end and your account is a Premium one. Do you still need any help?
-
Hi @Suty, it's a Samsung Galaxy S20 5G (SM-G981U1)
-
@gavin-swonnell yeah! Mine too!
-
Is their any data published on the accuracy of this model for forecasting wind, sun, rain, temperatures out to 15 days?
I find your description of the model contradictory. At the beginning it's touting using this model plan for future activities with more accuracy and at the end it's stating forecasting out 15 days is risky and caution should used for planning activities around it. Would be good to know the positive predictive value when it forecasts a windy day on a certain body of water 15 days out (ie what % of the time that it predicts a windy day does it turn out to be correct) and likewise what is the sensitivity (what percent of windy days does it truly pickup 15 days out).
We recognize predicting weather/wind is challenging but it would be helpful to know if the accuracy is a flip of the coin (50%) or more like 80-90%.
Thanks for all you have done with this great app!
