I haven't been down to Bronte yet this year, so I don't know for sure, but I'll tell you this: The warm weather and lack of rain has been stifling the salmon run across the board for the last week... Credit has been dead all week, I can't see Bronte being any better...
However, there was a little rain today and more forecast for this weekend along with a drop in temps, so maybe the run will pick up. It may be worth a shot, you never know.
Hopefully someone will chime in who has a first hand report.
btw, if you do go, can you please give us an update thx
