So, I have Met Office and the free Windy - but I'd be happy to pay a subscription if I thought there'd be enough benefit. What do people using here in UK particularly?
Certainly the important thing is not the “app” but the weather models used. And MetOffice (their own model) and XC (use GFS) are a decent combination - particularly if add Inshore Waters which seems to be a different view from Met Office.Met office and Xc weather app . Freebie. As accurate as any up to three or four days. Personally can't see the point of any paid Apps . Their basically all using same source info just different interpretation.
Short range i just look out the window. Lol
Windy is worth premium for me just for the distance & planning option. Plus has the 9Km ECMWF model, not sure if anyone does that for free.So, I have Met Office and the free Windy - but I'd be happy to pay a subscription if I thought there'd be enough benefit.

You do not say what you want to use the forecast for.So, I have Met Office and the free Windy - but I'd be happy to pay a subscription if I thought there'd be enough benefit. What do people using here in UK particularly?
You can’t get ECMWF using Saildocs free email serviceWindy is worth premium for me just for the distance & planning option. Plus has the 9Km ECMWF model, not sure if anyone does that for free.

(take it you mean 'can' get)You can’t get ECMWF using Saildocs free email service
Availability at about 0800 and 2000. You should get it a little earlier on paid for services but not before 0700 and 1900.
- 0 to 144 hours at 3-hourly intervals
- 144 to 240 hors at 6-hourly intervals
I should have said that Saildocs ECMWF output is a 0.4 degree res. However, noting that the model effective res is 0,5 degrees, there is little loss of information compared to, say Windy.com. In fact, we do not know what is the output res of Windy nor other models. Using XyGrib you can see data ONLY at the grid points issued by the originator. I have not seen that on other apps. They all interpolate so giving a false sense of resolution.You can’t get ECMWF using Saildocs free email service

Yes, I really meant “should be able to”(take it you mean 'can' get)
Free versions of ECMWF are limited. Saildocs only gives wind, MSLP, temperature. Plus, for those living in the past, 500hPa height.Thnx. Says 0.4Deg in Opencpn, is that the 9Km model windy does? Just tried it in opencpn, seems limited with just wind & pressure, no gusts.
ECMWF is a little more detailed than other models. Partly, that it is because it runs 2 hours later (only twice daily) than other models. It can analyse more data. The slight gain in performance is offset by the timing and the more frequent updates of GFS/UK/ICON etc. looking at the Windy comparison, I rarely find significant differences up to 5 days. When I do, I treat all models with th same caution.I find everywhere is different & it pays to watch the various models to see which one is consistently most useful but here in the canaries the ecmwf 9km from windy even without graphing the data does seem well ahead of the others in getting closer to the local effects round the leeward side of islands.
The windy 9Km ecmwf does seem to usually be very good at picking up the afternoon onshore winds which pick up over about a 15Nm southern coast here in Gran Canaria which presumably would be missing from the 0.4Deg model.I should have said that Saildocs ECMWF output is a 0.4 degree res.

As ECMWF Effective resolution is 0.5 degrees that is difficult to explain. From La Rochelle northward or, at least north of Ile d’Yeu we often found that the GFS got the sea breeze effect well. UKV can get the Solent sea breezes but may not/The windy 9Km ecmwf does seem to usually be very good at picking up the afternoon onshore winds which pick up over about a 15Nm southern coast here in Gran Canaria which presumably would be missing from the 0.4Deg model.
And agree with XYgrib display resolution, so easy to kid yourself, just read any weather app thread on here.
Randall Reeves said it well, weather forecasts might not be right all the time but they can be strongly suggestive
I assume that is UKV? Pretty good. It is similar to my use of the Met O app for rain. Someone might like to show this to Viago, Zoidberg and some others who were spouting nonsense in another, recent thread.Found this again recently which I made a while ago with some python code, met office actual wind and met office forecasts for a calibrated wind senor @ 10m on one of the Scillies, amazing the forecasts are usually as accurate as they are!!
