Weather is one of the most critical factors in safe seamanship. Wind strength and direction determine sailing conditions, sea state affects comfort and safety, and visibility impacts navi...
The Beaufort Scale describes wind force from 0 (calm) to 12 (hurricane). It links wind speed to observed sea and land conditions. For coastal and offshore passage planning, pay particular...
The BBC Shipping Forecast covers 31 sea areas around the British Isles. It reports wind direction (the direction it blows FROM), wind speed (in Beaufort scale), weather (rain, fog, etc.),...
High pressure (anticyclone) brings generally settled, fair weather with light winds. Wind circulates clockwise around a high in the northern hemisphere. Low pressure (depression or cyclon...
A warm front marks the leading edge of warm air advancing over cold air. It brings a gradual deterioration: high cirrus cloud, then lower cloud, steady rain, poor visibility, and a rise i...
Buys Ballot’s Law allows you to locate the centre of a depression from the wind you experience. In the northern hemisphere: stand with your back to the wind, and the low-pressure centre i...
A barometer or barograph supplies one important strand of short-range weather evidence. A pressure trend must be read with the current marine forecast, wind, cloud, visibility, sea state,...
At Yachtmaster level you should be able to sketch a rough synoptic chart from the general synopsis portion of the shipping forecast. This gives you a spatial picture of where highs, lows,...
Sea breezes develop on warm, sunny days when the land heats faster than the sea. Warm air rises over the land, and cooler air from the sea flows in to replace it. Sea breezes typically de...
BBC Radio 4 currently carries the Shipping Forecast at 0048 and 0520 every day, with an additional 1754 broadcast at weekends. The Inshore Waters Forecast follows the early broadcasts at...
Meteorology at Yachtmaster level is not just recall. The answer has to show command judgement, evidence quality, margin, and a fallback if the first plan stops being safe.
Decision pressure: Continuing may keep the schedule but remove safe options later.
