Water temp is warm during summer, about 30°C. In winter about 10-15°C. Air temp ranges from 14-20°C in winter to 21-32°C in summer. Wetsuit definately not required in summer but sun is fierce so rashshirt required. Season here runs all year.
Wind is best here in the afternoon. Best season here is spring with heaps of 20+ knot days from the West or SW (almost every day). Summer thermal breezes can occasionally reach this far east and are usually 10-20 knots. Afternoon winter winds are also quite good here from the WSW after the squalls has eased a bit. Even during autumn sessions here are frequent, despite May being the most flukey season in Auckland. Spring is very windy.
All wind directions work here.
Go to Pakuranga, then to Howick and then to Whitford. Drive North to the water and depending on the wind direction to the west or east side. Find a spot to launch.
