The final day of the year is 25% likely to have cloudy conditions. Deep night and early morning are periods of the day that are the cloudiest.

Extraordinary Weather Occurances

Northwesters may be the cause of rough seas during the winter (high) season, which put a stop to enjoying water sports. Occasionally, they may even damage vessels if these aren't anchored in safe harbors, and splash debris on the roads by the Grand Cayman coastline.

Also note that the Cayman Islands are in a seismic sensitive zone. But, the possibility of an earthquake occurring is very low. The last great earthquake, which caused a big damage, took place in 2004. Furthermore, earthquakes could lead to tsunamis, which are also rare. They are most dangerous by the coast where the waves grow in size. Hence, if it comes to that, remain on the open sea or go inland as quickly as possible. Taking some higher ground is also a good option.
