Just paid for the commercial version of Swellmap.com and I like what I see. Much more detail then Marineweather which has not been overly accurate for me.
For $7 a month, I believe it would pay for itself. Considering I often pay $50 in petrol to reach a fishing spot only to find that it is to rough to easily fish. I got a whole year (or maybe rest of year) subscription for $39.
Would let you guys know if it proves to be accurate.
Will be good to know how you get on with that, as i know to well the frustration from leaving blenheim with no wind at all only to head down the coast and find either big noreast swells or southerly swells that are way not fishable or on the other hand to have a heap of wind here in town only to hear from friends that the sea was flat the weekend before.
A good one would be today after knowing the southerly front went through what does the software say about the swell today (ps no need to tell us as youve paid for the software so keep that as your advantage aye heads up )
Use to use it before finding swellmap, but I have no confidence in marineweather. Swellmap rarely gets it wrong.
Another good page is http://www.predictwind.com, but the the free trial is about to end and it is expensive to subscribe ($100+ a year), it is targeted towards sailers which probably explains the cost. But the info is good. I have been known to check Predictwind during a norwester at home, checked the signs and notice it is calm by 7pm, arrive to the sounds for perfect conditions Going to miss it.
