if we are planning a kayak trip,
we use 3 sites,
XC , weather,
the MET
and magic seaweed
+1
Those tend to be much more accurate & are updated many times a day.
The general BBC stuff is not usually as good for they pay much more money for them than the BBC.
At the best the BBC is only good for two days if you are looking for a regional accuracy . It used to be that the BBC showed the isobars and direction of movement
Now it's been dumbed down so it is cheap and also allows you to make a cup of tea whilst it's on.
Your sites are ideal for planning sea angling trips a week of so ahead , as you can see the arrows showing weather & wind movement patterns & see the temperature of the fronts.
