The internet is amazing. When we first moved to Long Caye in 1996, there were no on-line tools for watching the wind and waves off the coast of Belize. Now there are a whole host of websites that we watch to check the swell and wind. If you are planning a Belize surfing trip, you will want to check out the sites that we use.
Magic Seaweed! Our #1 favorite (screen shot in the image above), you can check swell, wind, sea temperature, pressure and period.
Swellwatch This one is cool because the maps are actually zoomed in to Belize.
Swellwatch also has a satellite image for the entire Caribbean coast.
And I love the graphics on Stormsurf, look at the waves streaming through the channel between Hispanola, Puerto Rico, and the Virgin Islands!
Swellinfo We also regularly refer to this one, even though it has Cancun surf, not Belize. We have to extrapolate a bit to use it.
