Blaketown Wedge • Surf Spot Statistics

Best Surf Season (May - August)

The heart of the action at Blaketown Wedge comes with the southern winter, when the Tasman Sea and the Southern Ocean are firing on all cylinders. Average swell heights push 2.0m (6.5-7ft) and mean wave periods climb to 12.0-12.4s, giving the northwest-facing Wedge the long-period groundswell it needs to light up. During these months the wind distribution tilts decisively towards the E/ESE quadrant - especially in June and July, when the ideal offshore wind percentage tops 70 percent. The result is clean, powerful and consistent surf, with plenty of 1.5-2.5m (5-8ft) sets rolling through. This is the closest you'll get to machine-like consistency on the West Coast, and the cold winter air is a small price to pay for the quality.

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

The shoulder months either side of winter still deliver a serious amount of energy, with average swells ranging from 1.7 to 2.1m (5.5-7ft) and periods in the 11.9-12.3s range. The Tasman remains a hive of low-pressure activity, spinning up WSW and W swells that directly strike the Wedge's exposure. Wind is the deciding factor - the ideal offshore wind percentage drops to 36-53 percent, so more days are compromised by onshore W/NW flow. On the best days, a low-pressure system near the South Island will drag a clean ESE breeze out of the local valleys. When that happens, these months can produce some of the biggest, most photogenic wedges of the year.

Low Surf Season (November - February)

Summer puts the Wedge in a mixed bag. Average swell heights ease to 1.6-1.8m (5-6ft) and periods fall back to 11.0-11.7s, meaning less push and less organisation. More critically, the wind roses show a strong dominance of W, WNW and NW flow - exactly the onshore directions that wreck the shape. The ideal offshore wind percentage slides to just 30-37 percent, forcing surfers to pick through the calendar for a morning ESE or a day when a transient high parks itself in the right place. February and January offer the warmest water (17-18°C) and the longest light, so it's not a total write-off, but consistency is rare. If you're chasing the Wedge at its best, save your leave days for the winter.
