Bula! We just returned from Lalati on the 21st of June. I think I met h2o2 on the 19th, there was an Italian couple arriving.
The water temp was 79-80F on every dive, that's warm enough for a skin and fleece hood for me. Air temp about the same. The resort staff, dive staff and management are great. We had 28 folks, with 24 divers and worked with us at every turn to accommodate the group.
We saw sharks on almost every dive, but definitely do the shark dive, words cannot describe the event. I did the dive twice. One tip, if you have a camera, don't use the flash. The backscatter and masses of close fish will under expose the sharks in the distance. Also, try to get at the end of the line of divers, in the center, the swarm of fish will block your view of the sharks. On the end, you can clearly see the sharks as they enter and exit the swarm. The DMs said they haven't seen the Tiger shark for a couple of weeks. They suspect he may have been finned, it still goes on in the area. During our dives we saw White Tip, Black Tip and Gray Reef Sharks. On the shark dive, along with the reef sharks, add Silver Tip, Lemon, Bull and Nurse sharks.
We had 8 teachers in our group, they enjoyed the trip to Waisomo village to visit the Beqa Island school. Be warned, they will sing a song for you and will expect you to reciprocate. One of our teachers stepped up and organized rounds of "Row, row, row your boat."
Several of us went to Lalati Village and were treated to a Kava ceremony. Be sure to take the sunset cruise and talk the captain into going to Bat Island when the flying foxes are leaving for the night.
What did we see in the water? The only thing I was looking for and didn't see was a frog/angler fish, otherwise we found the rest. Including sea snakes, giant clams, and blue ribbons eels. More nudibranchs and butterfly fish species than you can shake a stick at. Definitely, do dives off of the pier, (the water was clearer when the tide was coming in) and follow the reef to the left. There is a blue ribbon eel at 22 FSW (high tide) and a LARGE grouper.
