Just wondering if you can dial in report and find out what way the sweep is running on your local beach? It could help when winds are borerline?? Is it linked to ocean currents???
If the wind has been from the N or NE for a few days the sweep is usually from the north to the south
and if its from the S or Se the sweep will more than likely be from the south to the north
There is usually more sweep at high tide than low tide due to the water being deeper

Inshore currents generally run with the swell direction on the east coast which is predominantly South to North. Depending on the topography of your beach, they will change and run with the wind after it has blown strongly. Hence the period when the sea breeze first kicks in on the east coast (northerly) and the current is still acting in your favour (against the wind) you are going to feel more powered up. Conversely a stong southerly wind and current from the same direction will Be harder to hold ground. This is noticeable in large surf conditions in SE winds on the North coast NSW and SE QLD. Throw in some headlands and rivers and local conditions apply. Inshore gutters, sandbars and outgoing tides also play a part. So basically you will have a current moving south to north that will swing with a half a day of a strong northerly on it.
