Conditions at Smiths Beach in May
May: The Southern Ocean Wakes Up
May marks a clear step up in power. Average swell height climbs to 7-8ft (2.3m) with an average period of 12.9 seconds, and for the first time in the climatology there is a meaningful sprinkle of WNW/NW/NNW swell in the mix. Those are the angles Smiths needs, so the new winter groundswell can finally push through to the beach with more authority. The dominant SW/WSW remains, but the westerly spread has widened.
The trade-off comes in the wind. The subtropical high has shifted away and frontal systems now arrive with muscle. W/NW winds become much more common, and ideal offshore flow runs at 26 percent. You need to catch the post-frontal S/SW window before the next low approaches. Water is cooling to 20.4°C and rainfall climbs to 2.70mm/day, a sign of the storm track waking up.
