FORECAST GUIDE

Reading the Atlantic Graphics

Each row follows the same 24-, 48-, 72- and 96-hour progression so changes in the synoptic pattern and marine environment can be compared through time.

500 mb

Shows the mid-level height pattern used to assess troughs, ridges and large-scale steering flow.

Surface

Shows forecast highs, lows, fronts and the surface pressure pattern.

Wind & Wave

Combines marine wind information with significant wave-height forecasts.

Wave Period & Direction

Highlights the period and travel direction of the most energetic wave systems.
