Conditions at Spiders in January
January: Prime Midwinter Groundswell
January is peak season at Spiders. The average wave height is a solid 7ft (2.2m) and the average period of 13.3s means real, long-period Atlantic groundswell is unloading on the sandbar. The swell rose is heavily loaded toward NW and NNW, with those two directions combining for 61 percent of all wave energy and another 10 percent wrapping in from WNW and W. That means plenty of size, but also an emphasis on slightly north-of-ideal swells; when the direction shifts into WNW proper, Spiders goes to its highest quality. Winds are the best of the winter as well, with an ideal 57 percent offshore wind count. E and ENE winds contribute 22 percent of the wind rose, while westerly wind directions stay very low. Air temperatures average around 14C and water is 17.2C - a 4/3 or 5/4 wetsuit is your friend. January delivers when the North Atlantic really snaps.
