Default XM weather

Quick question-- I have XM radio on my car. Anyone know if there's a simple upgrade to get the weather radar on the boat?

Different antenna, different plan. And depending on your chartplotter, may need a separate weather module.

What kind of electronics are you running on the boat, that's a good place to start.

The satellite weather is a great safety addition for the boat. I use mine all the time.

Got a small Lowrance 5 inch screen (forget the model number right now) but getting ready to upgrade. Looking to spend in the $1200 range and trying to decide on getting some type of weather package.

I am considering a HDS5 just to add the weather. Dont need depth finder.
I am most interested in wave height offshore Tampa.

Question: On this size screen will I be able to read the wave heights, or will I need my magnifying glass to get that info?

Of course Im interested in tracking fronts and lightning strikes, but I didnt think I would have a problem seeing that on the display.

Secondly, since I dont really need gps charting info from that unit, will the display be as effective if I buy a unit with base maps only?
I'm thinking if I can see the west coast of florida land mass on the display, I should be capable of tracking storm fronts adequately.

I have two other gps units with depth already and I don't want to change out either one. They just are not capable of receiving Sirius weather offshore.

Has anyone got a screen shot of a 5" display showing the wave heights?
In your experience, are the wave heights somewhat accurate?

If anyone has an HDS 5 and they want to upgrade, shoot me a PM with a price and description. I don't need the transducer and I can buy the weather antenna retail.

Thanks for any help

fshmn ....

This is how wave heights are displayed on my Simrad NSS8 (the presentation is the same on the Lowrance). The darker shades indicated higher sea states). You can also turn a color legend on that will give you an estimate of sea states OR you can move your cursor around the screen and get a numerical value of sea state by lat/long of the current cursor position.

In the screen shot you can see black arrows they indicated wind direction you can also see NOWRAD data superimposed over the wave heights display.

These are actual weather events .......



Here's a larger geopgraphic display of wave heights.




Here's an SST display ......



Here's an expanded NOWRAD display front with assoicated TS's.

Can you see the same info on your Garmin, even if it's in a different format?

BWP, thanks.
Your web page videos are very nice.
If I understand correctly, you do not get a numerical wave height on the chart, you get a color shade signifying the wave height?
But, if you put a curser over a location, it will give you the wave height numerically?

What model Garmin are you videos taken from?

What I am confused about in my few offshore trips would occur when "Windfinder" predicts 1.5' waves, which doesn't sound like much, but seems to ignore swell height.
I get 25 miles out expecting to see 1-2' waves and find myself in swells of 2-3' with breaking waves on top of that.

Does the Sirius Weather wave height include swell height?
Since my offshore trips take me more than an hour to get to the ramp and my trips are takinng another hour to get there, I would certainly appreciate knowing that it is really going to be 3-4' out there rather than 1-2'. If I knew that info, I would chose to fish within Tampa Bay rather than head offshore, wasting time and gas trying to get to a spot that is too uncomfortable for an old guy like me to enjoy.

Part of the problem is the swells/waves in the GOM off Tampa will have a very short frequency. Years ago when I lived in the Keys and fished in the Atlantic, I didnt seem to mind the 4-5' swells as their frequency was considerbly longer than what Im encountering in the GOM. Of course I was 30 years younger then and too stupid to be concerned about much.

Thanks for your info
