Whilst most of these sites
share similar information,
it is always usefull to cross-
check weather predictions.  
As all of the mentioned sites
are accurate 90% of the time,
they are prone to the odd
mistake or miscalculation.

A competitive angler always
has to know that he / she has
all the angles covered.  It is
always a sore sight to see
the wind change to an
unexpected and unfavourable
direction  or to see an
unexpected cold-front

appearing on the horizon.
