Mount Maunganui - surf spot statistics

Best Surf Season (May - August)

Winter delivers the most consistent and surfable conditions at Mount Maunganui. The Tasman Sea and Southern Ocean fire up with a parade of deep low-pressure systems, generating a steady stream of mid-period swell from the NE quadrant. Ideal offshore winds from the SW through W quadrant blow over 48% of the time, grooming the waves into clean, rippable lines. Average wave heights sit around 1.3m – solid fun-size to head-high – and though periods dip slightly to 8-9 seconds, the combo of reliable swell and favorable wind makes this the go-to window.

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

During the transitional months, the balance shifts. Swell directions remain favorable from NE to ENE, but the wind becomes a coin flip. The percentage of offshore wind drops to 40-44%, with more frequent onshore NE breezes mixing in. Swell heights average 1.1-1.2m and periods are moderate (7-9s). You'll find plenty of fun sessions, but you need to pick your windows – early mornings often score the cleanest conditions before the seabreeze kicks in.

Low Surf Season (December - February)

Summer brings the highest percentage of onshore NE winds – the same direction as the dominant swell. This creates a classic windswell scenario: waves are often bumped out, choppy, and less user-friendly. Ideal wind drops to 36-39%, and although the swell direction is perfect (NE-ENE), the lack of quality wind limits good surf. Wave heights average 1.1-1.2m with longer periods near 9 seconds – the potential is there, but you've got to chase the rare day when a SW wind change or a tropical low aligns.

November: Spring Stalemate

November is a month of highs and lows – literally. High-pressure systems often dominate, leading to smaller, weaker swell. Average height is 1.1m, period 7.8s, and the swell comes mainly from NE (19%), NNE (12%), and NNW (13%). The wind pattern is similar to October: offshore wind at 40% and onshore NE winds at 17%. However, the Westerlies (WSW and W) are still strong, blowing 35% of the time, often in the 20-30 kph range. These can create excellent conditions if there's any swell, but the fetch is often limited. Look for a marine heatwave or tropical low to the north that might send some longer-period swell. Otherwise, it's a month of small, clean mornings and bumpy afternoons.
