North Africa data points

Postby jago25_98 » Sat Nov 08, 2014 10:53 am

I notice the forecasts get worse the further sound down past Europe you get.

In the UK the forecast are really accurate with only wind as the thing you really need to think about.
But as you get down past Europe and into Africa it's more of a rough guide only. Many tourist are reliant on forecasts and so get it wrong all the time. Some elements are more reliable than others. AFAIK swell direction is still pretty accurate. But wind often drops unexpectedly and also the swell size is very often way off. I've seen a 2' forecast go to double overhead in an hour.

What are the forecasts based on? What bouys are used? I can't see around North Africa.

Isn't there a map of NOAA bouys outside of the north sea?

It would be good to be able to see yesterdays forecast to be able to compare.

Same situation again, this time with New Zealand and Australia. Probably also effects Tahiti.

There's basically no buoys in the whole of the south pacific:

I guess the forecasts are more reliant on satellite data. However, from experience I am noticing that the satellite data doesn't seem to be as reliable as buoys being an additional source.

NZ is particaulrly interesting. The forecasts here are very hit and miss. I wonder if the lack of buoys has much to do with it rather than it being difficult to predict. There seems to be a pattern where lack of buoys make for bad forecasts. I could be imagining it... would be interesting to know for sure.

USA magicseaweeders, especially atlantic I'd like to know your experience of this because USA is really the only place to have good coverage a bit like the UK to compare to.

It baffles me that nations can't be bothered to stick a buoy in the water. I would guess they think satelites are just as good... when in fact they're probably not.

A satellite can measure within 4cm according to google which I believe is more accurate than a buoy?
