Just a precautionary FYI for anyone already in or traveling to PV for the next few weeks.
The ocean currents are changing, it happens twice a year. Around Oct. the currents change and flow from North to South, cooler waters start flowing South. In March/April the currents change direction and flow from South to North bringing warmer waters and the conditions that allow for tropical storms and Hurricanes to form in the Pacific Ocean. If you look at the dates they also coincide with the whales migration. They swim with the current, not against it.
This time every year (around Semana Santa) there is an increase in drownings. Underneath the surface the currents are churning like a raging river as they are changing direction, everything looks smooth on the surface but it creates rip tides and undertows. Undertows pull you under, rip tides pull you along perpindicular to the shoreline and unless you are a very strong swimmer you can't get out if them. If you get caught in a riptide you need to relax, not fight it, yell for help and swim with it, you will know when it stops and you can then swim to shore. Why the increase in drownings? It is high season = more tourists, some have never begin in the ocean before, many Mexican Nationals come for vacation and can't swim. When it changes in Oct. it is still slow season = less tourists swimming in the ocean.
This is also the reason several people posted how rough the bay was coming back in the afternoon on the water taxis from Boca, Yelapa, etc., and the reason the waves can be bigger around Los Muertos (it is the way the waves break in that particular area).
Can you still swim in the ocean, of course you can, just be aware and don't swim out far from shore. Don't let the fact that you are in a bay fool you, the currents still flow through the bay.
