There is no pre-reading before this section of the course.
Why is this important?
Before you go to sea you don’t just need to know what the weather is like now but what it is going to be like for the time you are at sea. You need to plan for what the weather is likely to throw at you and be prepared not to go if conditions are beyond your’s, your boat’s or your crew’s capabilities.
The primary weather forecasts for UK waters are issued by the Met Office and are divided into the:
– Inshore Water Forecast (up to 12 miles offshore)
– Shipping Forecast (Eastern Atlantic from Portigal to Iceland)
If you here the Shipping Forecast on the radio you can use this form to copy down the information.
It should be noted that these forecasts are all general forecasts that often cover a large area. Particularly in the case of the Inshore Water Forecast the local weather can be radically changed by local conditions.
A frontal systems
During you course you will require a understanding of the construction of the “standard” weather system and the effect it will have on weather as it passes over you. in reality no two weather systems are the same but they they all include key feather in common.
