Just left on Friday (boo hoo) and did our last set of dives on Thursday. Water temp was 80 at the surface and 78-79 bottom (ranged between 50 - 90 ft depths) the whole week. My husband just work his swimsuit and a rash guard shirt but I opted for a 3mm core warmer with a full skin (I have really fair skin so I have to keep it covered). We planned to dive 7 days of 2 tank dives but only got in 5 days (2 days, 2 day break and 3 days). I was a little chilled on the last day but not so that I was cold or sucking up more air.
Vis improved by the end of trip and the day we flew out, it looked like things were getting back to "normal." The swells and wind were definitely calming down and I think WindGuru was forecasting good seas for the next week or so.
We dive with Flamingo Divers because we like the smaller boat (no more than 8 divers max) and love Mickey and Jayne but Caicos Adventures has a good reputation. They have a larger boat so I think they were able to go out on the days when the seas were over a meter.
The extra topside time gave us a bit more opportunity to explore the island. Yes, it's low key but we love that sort of thing (we're the dorks who download our dive photos to the laptop and start color-correcting them that night). Grace Bay definitely is where the "action" is if you are looking for bars and clubs and the like. We stayed over by the southside marina at Harbour Club Villas and like having a villa to ourselves. Grace Bay is a gorgeous beach but there also is Chalk Sound, Taylor Bay, Leeward Pass Through and Malcombe Beach for some beautiful views. Also southwestern harbour bluff is quite beautiful and has some very good snorkeling when the weather is good.
In terms of dive sites, my husband and mine's personal favorites are The Gully, Coney Island and Rock Garden Interlude. The Gully has a nice dramatic swim through (it's more of a canyon/cut than an overhead environment) and beautfiul sights along the lip of the wall. Our last dive there, we were kept company by a male and female reef shark who were cruising around (on a previous trip, we got to catch a glimpse of a hammerhead as we came out of the swim-through). It's a very "fishy" site so there are lots of large schools that circle around the coral heads. Coney Island and Rock Garden Interlude are good second dives with lots of marine life to see. We usually saw sharks on those but the more interesting stuff is the smaller fish, cleaning stations, etc. (which I know isn't every person's fave). We did get a chance to get over to French Cay and dove G Spot and Rock & Roll- actually swapped sites with the Aggressor. We really liked the wall there - reef looked in better shape but vis that day wasn't spectacular.
Oh by the way, Big Blue reported hearing whales over at Northwest Point. It's a bit early for that but here's wishing you luck! Have a great trip!
