Rating information for Boating

This rating is a guide to determine how pleasant the boating conditions are likely to be. But this should not be treated as a substitute for using all available sources of information for the purpose of safety.
A green rating between 7 and 10 indicates calm waters, based on little or no wind, and swell height less than a metre.
An orange rating between 4 and 6 indicates average boating conditions, possibly affected by light-fair winds, and a swell height around 1-2 metres.
A red rating between 1 and 3 suggests poor and possibly dangerous conditions such as strong winds and a big swell height 2-3 metres plus.
No rating available.
