The weather may not be getting any better, but marine forecasting has taken a big leap forward. In short, giant advances have been made in forecasting and it is worth the effort for sailors to learn to make the most of them. But if you want to join Franklin’s cognoscenti, a bit of time spent perusing the NWS websites will help you learn how to analyze 500mb maps, decode Skew-T charts and translate the symbols used in every Surface Analysis and Forecast. The former lets you know whether to bring an umbrella to work, and the latter can tell you a lot about how an approaching surface low will behave, where it’s headed and the likelihood of major intensification.įor many, the latter may seem way too arcane. Most agree that there’s a big difference between a newspaper weather map and a 500 mb weather forecast. The weekend sailor might be satisfied getting severe thunderstorm avoidance strategy on traditional VHF weather watches and warnings, while the ocean voyager/amateur meteorologist might be interested a full Skew-T chart, a complex chart used to illustrate weather trends using temperature, dew point, wind speeds, and more. Which resources to tap depends upon your weather awareness and your need and desire for details. Even sailors in low-lying coastal areas can become attuned to the reliable wind shifts near points, tall buildings, or cuts where the surface winds are altered by land features. Mountains can produce dramatic wind shifts and powerful gusts that the sailor needs to watch for. No matter how much weather information sailors have available, they will need to be conscious of local patterns, especially the impact of topography referred to as an orographic effect. These sources use a wide array of detailed surface and mid-level atmospheric data to make forecasting accuracy far better than it was just a decade ago. For ocean voyagers and passagemakers looking for personal weather consultation, there are professional weather routing services such as Weather Routing Inc. In addition to the free products from NWS, there are third-party products and broadcast services such as Sirius XM and Theyr. Both are available free of charge from the National Weather Service (NWS). They can be enhanced by a forecaster’s practiced eye, or be derived as a computer-generated, gridded binary (GRIB) file (see “ Getting Weather at Sea,” PS April 2020). Today’s forecasts are available in text, voice, and graphic formats. north, 3.Benjamin Franklin is credited with the quote “the weatherwise and the otherwise.” It remains savvy advice for all sailors, and thanks to modern oceanographic and atmospheric science, becoming one of the “weather wise” is easier than ever before.
