      @Polina-Nozdrina Why is the AIFS model limited to only ~7+ days out?

        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,
            Gavin

                You get the 15 days only in point forecast table, not in the map.
                Here shown on 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

                            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.

                                I can't make the payment smoothly. I've never used such a crappy payment system.

                                          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!

                                            Greate, Perfect application for an AI.
                                            Will also the current prediction be better with the AI ?
                                            Re. The operation of the AI,

                                            • will the AI operate with constantly fintuning or will the AI training be updated as software in general, ie in steps as new releases?

                                            For paragliding on a specific spot many times its possible understand how the local whether usually deviate from the forecasted .

                                            IF the AI take in to account the actual weather at a spot, the local variations at this spot ought to learned by the AI.
                                            Correct?
                                            Then the AI also ought to make better forecasts for that specific spot even in the short and medium term forecast,

                                            I usually look the predicted weather for a place and a specific day. I then follow how the prediction changes day by day. Then it's possible to see a trend in how the forecasted weather changes. This give me a hint on how the predicted weather for that day and place is most likely to change if changed at all.

                                            • Is this a valid way of interpret the possible the forcasted weather i.e. the possible changes in weather compared to the predicted original prediction?

                                            Is there any way the see the calculated certainty of presented forecasts?
