Apologies if this is old news ...... but I just tapped on the screen of Android tablet to after updating the Navionics app to check something and the cursor which appears on screen with a question mark now has a new weather symbol which was not there yesterday.

I tap on the weather symbol and get current weather, wind, pressure, visibility etc at that location plus 24 hour forecast plus 4 day winds with animation plus 7 day forecast plus 24 hour tides etc etc. (scroll down for detailed winds, tides and currents)

Assuming it's an accurate forecast from The Weather Channel then that's an excellent addition. :)

Thanks for drawing that to my attention. However my Navionics app is clear that the feature comes with Navionics+ subscription (which I do not have). Still, it was happy to show me the sun and moon rise and set times for the location (Gulf of Corinth).

That's very strange Mike.

Mine is just the standard Navionics Boating HD running on an Android Sony Xperia tablet.

I have only one module called "Advanced Map Options" which was a one-off cost of a couple of Pounds which I installed a couple of years ago when I first got the tablet but all that does is give me access to a lot of depth setting and contour options. AFAIK it's nothing to do with this new meterology stuff and it definitely isn't a subscription of any kind. :confused:

On my iPad this feature comes up saying it is available through Navionics Plus

Not a big deal anyway. Not sure why I would want Navionics to gather weather data for me rather than choose what and when to gather weather data directly from the relevant sites.
Lots of organisations want to be your "portal" to get other data - very rarely is this beneficial to anybody other than the portal provider

As you're not bothered I guess this post is in case anyone else is.

Tap on the weather icon, when you get the first screen just swipe up for access to weather, tides and currents.

Other sources are available.

Ah, of course, swiping. Since Android think it is un-cool to show scroll-bars unless you are in the middle of swiping, there's no way to tell if there are gems just off-screen, without suck-and-see...

iPad too. I actually think that this is a very underhand way to encourage you to upgrade to +.

It really is not obvious and I can see no reason for the need to swipe up ... the screen could have been sized accordingly.

Cheap trick Navionics!
 
I had no idea these functions existed on my iPad Navionics. Just been playing with them and the wind arrows (presumably grib derived?) will be very helpful as will the tides. Thanks to the OP for mentioning them.
 
From the above, it is not clear to me if this is a free service. There are many ways of getting free US GFS information. Also, 4 days is a bit limiting. As I have said om another thread, I want to see GFS model output out to 10 days in order to be able to think and plan ahead for the next 5 to 7 days. Also, I prefer to see output straight from the horse's mouth rather than some interpolated point values.

I assume Weather Channel uses the GFS but would rather be sure regarding the provenance of any forecast. For most sailing purposes, you will not better the GFS overall. Others may equal or beat it from time to time but, at present it is the most reliable of all GRIB or similar services.

It's both free and accurate. Of course it is no substitute for a marine forecast ... see the fog forecasted (and actual), but as part of a planning overview it's very impressive.

Thank you. It can be no more accurate than the GFS – which it most probably is. The only differences between many GRIB or GRIB derived services are in presentation and availability of information.

As you say, such forecasts are great as planning tools. That is why I advocate starting looking 10 days ahead. When forecasts verifying at the same time on 2, preferably 3 consecutive forecasts 24 or even 12 hours apart, are similar then we start to think and plan ahead seriously. We look for continued consistency or, sometimes, a slow trend in the forecasts. When consecutive forecasts 12 or 24 hours apart are different then the situation is uncertain. That may sound negative but it should be useful to know that you should not then be planning ahead with any confidence. Sometimes you can plan about 6 or even 7 days ahead. At other times 2 or 3 days can be uncertain. It is in forecasts over the next wee that there has been most improvement since I last had to stick my neck out professionally.

GMDSS services cannot give the detail that we experience. Treat them as headlines and as warning services. Read them in the context of GRIB data.
