⚠️ Safety & accuracy
Before diving at Peavine Pass, always check the site-specific wind/wave forecast, tide/currents, and recent reports ! Reminder: Winds (even offshore winds) can impact slack time.
Briefings may be out of date or have inaccuracies. Dive within your training and experience. The first time diving a site, join someone familiar with the site and/or start on a mild day.
