Flags at the ferry ticket office, a short ditance away were not affected by this wind storm and always last much longer than any flying at Swallowtail. A flag that I have that is brought in each night lasts for years but has to be replaced, not from wear but because of fading.
The extreme wind was another reason for the board walks that used to connect the keepers house to the lighthouse, something to hold onto when moving between the two buildings but even those were at risk and were sometimes blown out of place and damaged in severe gales.
Here are a couple of shots of a windy October day. Northeast wind whips up seas quickly. With some wind storms, the spray can actually go over the lighthouse, hence the cables that hold the tower from toppling over.
