About Chen Rio
A reef dive. It goes down to 18 m. You get in from the shore. It suits Advanced divers and up, as a dive guide states it. The coast faces SE: swell from the SE reaches it, and wind from the NW blows out to sea. No dive centre within 10 km, the nearest 16 km away. The sea is about 27°C in January, its coldest month (3 mm wetsuit), and 30°C in August, its warmest (rash vest or 1 to 2 mm). For Advanced divers the best months are usually July, August and September, with about 7 good days in 7. From the weather of past years. The town to stay in is Cozumel. Within 5 km we also list 2 surf spots and 1 dive site.

What you might see
Too few open records near this site to list its animals. Ask a dive centre what you are likely to see.
This week: visibility over 30 m, about usual for the month (satellite plankton reading, 24 Oct). Estimated from the month's typical visibility and this week's satellite chlorophyll against the site's normal; heavy rain before a dive can still muddy it.
The current and the life no free forecast gives. Ask a dive centre before you book.
