Analysis

The North Atlantic is currently showing a moderate sized low pressure mid-way between Newfoundland and Ireland, which has been deepening over the last few days but is now starting to weaken. A short fetch on its southern flank is generating a pulse of westerly swell, currently forecast to reach the contest area sometime late Saturday. A band of high pressure extends from the Azores to the Bay of Biscay, meaning light wind conditions over the contest area. This is expected to persist until Sunday when a new low just west of Ireland could generate some westerly winds in Biscay. Forecast reliability is good for the remainder of the contest period.
