SORRY, BUT I MUST INTERJECT HERE:
I lived right on the Playa Coson for two years. Yes there are at times perfect waves (never lgr) but perfect for surfing. and Yes, Sadly I was in the vicinity when two young girls drowned one day. Turns out they were from the capital and had never learned to swim. & again Yes, at times mostly in the winter at that end of Coson there are very strong rip currents/tides due to the fact that the coast line turns into sheer rock cliffs that extend west towards the new airport El Caty.
I am sure that both Mountain Annie & Juniper have spent many wounderfull days at the Playa Coson and would say that it is one of the most beautifull beaches in the area ( you both may correct me if i am wrong), But in defence of the Playa Coson, the majority of the time and all the beach that extends from the Dos Rios east towards Punta Bonita is one of the safest and most pleasurable places to swim and enjoy the beaches of the peninsula.
When you have the chance, come & enjoy and be safe.
