We can also add a colour bar to help describe the figure, with a little more code:

import mpl_toolkits

matplotlib.pyplot.figure()
fig = matplotlib.pyplot.figure(figsize=(12.0,4.0))
ax = matplotlib.pyplot.gca()
im = ax.imshow(globaldata["hs_avg"][0], extent=[0,360,-90,90], origin='lower')

divider = mpl_toolkits.axes_grid1.make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)

matplotlib.pyplot.colorbar(im, cax=cax)
cbar = fig.colorbar(im, ax=ax, location="right", pad=0.02)
matplotlib.pyplot.show()
