- Large and powerful surf conditions for the rest of the day are expected to be hazardous for coastal activities such as crossing bars by boat and rock fishing, particularly for south to southeast facing beaches.
- Weather Situation
- A low pressure system lies over the Tasman Sea while a ridge extends across the state, maintaining fresh, gusty southerly winds and large, powerful waves across the coastal waters. Winds and waves are forecast to ease gradually later today through Tuesday as the low tracks further southeast and weakens while the ridge becomes the dominant feature over the coast. Then, another trough is forecast to sweep the coast midweek, bringing a southerly change in its wake.
