An Introduction to the Wind & Wave Chart

Seminar begins with an important discussion of the marine oriented strong wind & small craft advisories, watches, & warnings system used by the Environment Canada & the U.S. National Weather Service’s (NWS) Ocean Prediction Center (OPC), National Hurricane Center (NHC) Tropical Analysis & Forecast Branch (TAFB), & the Honolulu Forecast Office (NWSFO HNL) marine program. There will be a detailed discussion of the universal station plot of surface weather observations from ships at sea, fixed moored buoys, & land stations that report sea level pressure, winds, & present weather conditions, the bases for the OPC’s Surface Analyses Pressure charts. There will also be an overview of the key synoptic scale surface pressure weather system’s symbols (e.g. low & high pressure) & their associated features (e.g., fronts, troughs & ridges, & squall lines, just to name a few), challenging boaters as to what they know versus what they not know about them. Attendees are strongly encouraged to enroll in the prepaid 2.5-hour “Surface Pressure Workshop” that follows & is scheduled at 3-5:30 PM which will go into more in-depth detail of the Surface Pressure Analyses & Forecast Charts & the specific weather conditions a boater can expect (e.g., clouds, precipitation, & winds).


Lee Chesneau is a senior marine meteorologist, lecturer, & author. He is a graduate from the University of Wisconsin (Madison) where he earned a B.S. Degree in Meteorology.  Lee had a distinguished & extensive career with NOAA’s National Weather Service (NWS) & Satellite Service. He also served as naval officer in the U.S. Navy, a “Route Analyst” for a commercial weather & ship routing company. Today, Lee is an accomplished U.S. Coast Guard certified instructor for basic and advanced meteorology at number of continuing training institutions for professional mariners. He offers the same curriculum to educate & train recreational boaters on becoming self-reliant in their own marine weather knowledge for application in marine weather forecasting & strategic vessel routing.  See his webpage  He can be reached by e-mail:
