K59 - surf spot statistics

Best Surf Season (November - February)

The heart of winter delivers the most consistent surf at K59. Strong high-pressure systems over North America frequently push cold fronts into the Gulf of Mexico and the Caribbean, generating long-period SSW groundswell that wraps perfectly into the beach. Combined with a robust offshore flow from the N to NNE quadrants, these months see the highest percentage of clean, lined-up waves. Average swell heights hover around 1.0-1.2m with periods of 12-13 seconds, offering a mix of fun-sized rippable walls and occasional pumping sets. The combination of reliable swell and favorable winds makes this the prime window for surfing K59.

Fair Surf Season (March - April & October)

As the seasons transition, the swell machine keeps churning but the wind patterns become slightly more erratic. March and April see an uptick in average swell height to 1.1-1.2m and periods lengthen to 13-14 seconds, meaning more powerful groundswell from the deep South Pacific. However, the percentage of true offshore wind drops to the mid-50s, with occasional spells of lighter variable winds or afternoon sea breezes. October also falls into this category – the early arrival of winter swell is tempered by lingering tropical moisture and lighter winds. Still, when the conditions align, you can score some of the best waves of the year with long, clean lines and plenty of power.

Low Surf Season (May - September)

During the summer and early fall, K59 still receives abundant swell – in fact, average wave heights peak at 1.3-1.4m with periods of 13-14 seconds, thanks to persistent Southern Hemisphere storm tracks and the occasional tropical cyclone. The challenge lies in the wind. Offshore flow from the north becomes less frequent, with ideal wind percentages dropping to the low 50s. Light onshore breezes from the S and SSW can spoil the shape, making conditions mushier and less defined. Still, the swell is never gone, and savvy surfers who time the early morning offshore windows can score surprisingly good, powerful waves – especially during synoptic setups that bring a strong high-pressure ridge southward.

December: Peak Offshore Reliability

December caps the year with the highest percentage of ideal wind: 70%. NNW and N offshore flow dominates, with NNE at a massive 31.5% (mostly 10-20kph). Swell averages 1.0m at 12.2 seconds, but the consistency is superb. SSW swell accounts for 63.4%, S for 22.7%, and SW for 5.5%. While the average height is slightly lower than summer, the wave quality is second to none – clean, lined-up, and punchy. The 1-1.5m range holds a solid 28.6% of SSW, and the 1.5-2m range appears at 0.3%. December delivers classic K59 conditions: offshore winds, consistent groundswell, and a welcoming wave face.
