Yes-Blakeney and the Indian are good to go, many people have already been out already at these locations. As for Pakenham I’d have a really hard look at the nasty keeper hole below the ledge below the surf wave you mentioned. Many people have drowned in that hole and personally, I would never surf there.
On a better note, the rapid above the bridge in Pakenham is great for a after work spring warm-up run. It can be accessed on Jessie Street and contains some eddies and great ferries. And it’s near the best thing about Pakenham….Scoops ice cream!!
