Mavericks Surf Season
California, USA · part of the Mavericks spot guide
Mavericks is a rare-day, deep-winter wave. The season runs roughly November through March, peaking December through February, and even a good winter may deliver only a handful of genuinely epic days — the reef only truly turns on for a large, long-period WNW swell, and everyday NorCal surf does not wake it.
The old Mavericks contest window of November 1 to March 31 encoded that consensus: like The Eddie in Hawaii, the event only ran on a green-lit giant swell inside the cold half of the year, when the North Pacific storm track is strong and well aimed.
Where the swell comes from
The engine is the North Pacific winter storm track — the Aleutian low and its deep extratropical storms (and, in autumn, the occasional recurving West Pacific typhoon) generate the long-fetch NW groundswell the reef needs. Those systems are only strong and well-aimed in the cold season.
Historic swells at Mavericks
Mavericks arrives on the world stage
A powerful winter NW swell brought global attention to the wave; it was also the day big-wave pioneer Mark Foo lost his life here, a sober marker of the spot’s consequence.
The El Niño contest
The invitational ran on a spectacular, clean and huge El Niño-charged swell, won by Greg Long — a canonical big-and-clean Mavericks day.
"Code Red" / Day of Days
A huge long-period WNW swell coinciding with king tides produced what many called the best Mavericks day in two decades, redefining the modern paddle-and-tow ceiling.
Once-in-a-decade WNW swell
A record-class swell built from ~15–16 ft at 15 s to readings past 23 seconds, throwing 60–80 ft faces on one of the greatest days in the break’s history.
