Prevailing Wind

The wind direction most commonly experienced in a particular area over time.

This is based on local weather patterns and seasonal tendencies rather than the wind on a single day. Around the UK, south-westerly winds are common in many coastal areas, although local effects can change what is experienced on the water. Knowing the usual wind direction helps with passage planning, anchorage choice, marina approach and understanding likely sea conditions. Forecasts should still be checked, as actual wind may differ from the usual pattern.
