Mangamanu • Surf Spot Statistics

Best Surf Season (May - August)

The deep winter months are when Mangamanu lives up to its potential. With the storm track ramping up across the Southern Ocean, the average swell height climbs to 6-7ft (1.9-2.0m) and periods extend into the powerful 10.8-11.1s range. At the same time, the percentage of ideal offshore winds (W, WNW, NW, NNW) jumps to 70-78%, thanks to a persistent procession of lows moving through the Tasman Sea and a strong west-to-east zonal flow. The southeast-facing beach gets constantly groomed by clean offshore breezes while S to SSE swell wraps in with plenty of energy. Water temps are cold (10-13°C), but the trade-off is wave quality.

Fair Surf Season (March - April & September - October)

These shoulder months offer a taste of the winter bounty with fewer crowds and still plenty of swell. April and September both average 5.5-6ft (1.7-1.8m) with periods around 10.3-10.7s. Wind conditions are less reliable than mid-winter but still favor the offshore quadrant more often than not. The key is timing: when a strong front pushes through and the wind clocking to the NW, the surf can match any mid-winter day. Be prepared for more variability, as high-pressure ridges can park overhead and kill the wind, leaving lumpy, onshore NE-E conditions.

Low Surf Season (November - February)

Summer is the quiet period at Mangamanu. The subtropical high settles over the country, suppressing the storm track southward, and average wave heights slip to 5ft (1.5-1.6m). Wave periods also drop into the 9.1-9.8s range - rideable, but lacking the heavy, long-period punch of winter. Ideal offshore winds are less frequent (43-50%), and warm northeasterly sea breezes often kick up surface chop. That said, clean fun-sized waves are still on the menu when a passing trough drags a W/NW change through. It's a great time for beginners and longboarders, but those chasing power will look to the winter months.
