Thanks Eric and Kio - ive been trying for a couple of days and i just cant
seem to get my head around the interpolation or masked arrays. Would it be
possible for anyone to give me a few pointers on where to start editing the
script.
Ive tried digesting these tutorials the first one seems to be

It looks like with any reasonable contouring algorithm, this would
require interpolating into land regions, contouring, and then plotting
the land on top. The key is the interpolation, not the
IMHO that's the most straightforward approach.
He can use masked array for empty blocks (if contour data doesn't
already contain the holes as masked array) and apply inpainting, then
draw the land.

The present contouring algorithm works with rectangular blocks, and if

As the error message says, the problem is on Line 14:
print f.variables['WWSWHGT_P0_L1_GLL0']
a KeyError means that you tried to access an element that is not in a
dictionary. In this case f.variables is the dictionary and '
WWSWHGT_P0_L1_GLL0' is the element.

Hi Paul,
Thanks for your reply, I managed to fix it after I realised the mistake I
was making.
I've currently got a new problem. If you look at the image below, there's a
lot of white showing up around the coasts which ideally I'd like to remove.
The map is drawn using basemap, is there a
I think you posted the same image in both cases. Without seeing the
problematic image, I can only guess that it's caused by the resolution of
your data.

ok the file im using is this multi_2.glo_30m.t06z.grib2 from here
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/wave/prod/wave.20140109/ im
not sure its the right file to get wave heights of the North East Atlantic
so im trying different ones.
as you can see above in the top image there is some
What I'm saying is that your top image and bottom image are identical and I
don't see any white boxes in either. What is the resolution of the grid?

How does it look if you remove the calls to `m.drawcoastlines()` and `
m.fillcontinents()`?

Ive also changed the grib file from multi_2.glo_30m.t06z.grib2 to
nww3.t12z.grib.grib2 i still cant figure out which is the right file for the
North East Atlantic neither...i wonder if my data source is wrong..?

Looks like it's just a coarse resolution to me. Try showing the data as an
image with no iterpolation.

Thanks Paul i added m.imshow(data, origin='lower', interpolation='none')
Its made a little improvement but something still seems to be not right
