## What is Ocean Atlas?

Ocean Atlas puts the latest up-to-the-year satellite-derived climate data in your hands. So you can make the most informed choices when planning your ocean passages.

Climate change is here now, and is already impacting long-held understandings of ocean weather patterns.

Pilot charts based on data from 100+ years ago aren’t going to cut it any more.

In fact, any printed climate information rapidly becomes dated now.

Why make decisions based on outdated information?

Available data includes

• Prevailing wind rose
• % days with gales (average wind ≥ 34 knots)
• % days with calms (average wind ≤ 10 knots)
• Historical cyclones
• Average and maximum wind speed
• Average and maximum significant wave height

…with more on the way!
