Irish Sea, round trip

Best time to visit Irish Sea is summer. During summer months weather is more stable and equable than in autumn and winter. Due to passage of Atlantic lows, predominant winds are westerly winds. Sometimes due to high pressure extending N from Continent may persist for several days or even weeks and form easterly winds. Occasionally between July and September hurricanes from US coast may regenerate and cause some swell. Swell from W or SW is minor feature in St George’s Channel and in Irish Sea.

The effect of the flow of the remnants of Gulf Stream are not very significant in Irish Sea. However, 0.5 knots easterly currents should be taken in to account.
