As of right this moment:
Mexico is using this "stop light" thing to determine what can be opened, colors red, orange, yellow and green. Today was the first and only time I've heard referance to how they determine colors - something to do with cases per population and hospital beds - I've only heard that once so I take that into consideration.
Right now Q Roo is in red, the expect us to be orange on June 1st - Orange allows opening locally at a 30% rate - barbers, restaruants (still take out only I believe) and generally everyone. This time is to be used to prepare for when we change to yellow, staff is to be cleaning and prepping for tourism. The ocean is NOT open. There hasn't been anything said about what if any the curfew will be or if there will still be restricted travel (curfew now is 6pm and travel supposedly restricted)
They anticipate us to be yellow on June 8th which will allow reduced tourism. There hasn't been any clean definition of what that is - I'd guess reduced rates of service but wouldn't guess anything beyond that. We have heard the ocean WILL be open then.
A few points - watch where you get your information. Tourism groups have announced this and that, Xacarat has a letter out saying they are open on the 15th - until you see an announcement from the Governor, it just isn't real. Friday night at 10pm and nobody I know has officially heard that on June 1st I can get a burger at Hooter's, it's just how things operate here. I have an opinion that by some Mayan miracle, June 8th, we will be officially yellow and open but I really haven't heard how that is going to effect diving - there were rumors of 2 customers on a 6 passenger boat but again those are just rumors.
I know everyone wants to be the first one back in the water and it's easy fro me to say let this shake out for a few weeks, see how things progress, three or four weeks after they slightly open the place will tell us a lot of how things will be.
Everyone has their favorite dive shop, get in contact with them, see how they are going to handle things. I know people that run tours and people that own apartments, a few of them are not planning on opening up right away - check with your dive shop and see what they are planning to do.
