You'll get a better seabreeze when the city is predicted to be 25 with 30 out west. This is because the seabreeze keeps the city temps down. When it's 30 in the city, it's because we get hot N/NW winds associated with a following southerly front. It's all pressure related, sometimes we get strong prefrontal northerlies, sometimes not.
Having said all this, check out the noreaster that's just turned on at Kurnell.
