Great Weather Product

The good folks over at the Ocean Prediction Center have a feature on their weather-maps page to cycle through weather maps for the last 3, 7, or 14 days.

A great way to study how systems are moving and evolving over time in the area we plan to cruise or the ocean we plan to cross.

  • It’s important to understand that this is historic (before today), not forward looking.
  • It’s easier to understand what’s going on if we slow it down, or better yet stop it and use the buttons at the top to step through at our own pace.

Don’t let the historic nature of this tool put you off. Knowing what the systems have been doing for the last two weeks is invaluable when planning cruises and voyages.

And those who have taken the trouble to learn a bit about 500-MB weather maps will get even better insights by looping those maps.

Other useful options are to add satellite imagery and look at how waves and swell have developed over time.

A truly great learning tool for anyone who wants to really understand the weather around them, rather than just looking at GRIBs.
