This morning it was windy, then both windy and rainy, then the wind died and there was light rain for a few hours. Once the wind died, it was hot and humid. Eric cleaned the bottom.
The wind was forecast to shift direction, so he made sure that the anchor was well set, which was easy to do in such amazingly clear water.
This morning, the wind shifted back to the prevailing winds from the east. This meant we could finally go back to Thunderball Grotto. Coincidentally, this week Keith studied limestone rock and its erosion patterns in science. Thunderball Grotto was the perfect place to see the effects of erosion!
On Tuesday, April 29, after we finished our morning school/chores and were getting ready to leave Kosmos, it started raining hard — we did not want to be out in that kind of rain.
When it stopped, we checked all the rain forecasts to see if more was coming. They all said more rain, but conflicted with when it would hit and how hard. The clouds in the distance looked ominous, so we played it safe and stayed onboard for the whole day. It did indeed rain hard again, but not until the evening.
On Wednesday, it rained lightly in the early morning, but cleared up by mid-morning. After school and chores, we went to Thunderball Grotto. It was windy, and the ride over was a little bumpy and wet.
We anchored near the Grotto entrance, got our gear on, and jumped in. We took this video because we thought the sound was funny. We had no idea that it was significant.
