Cayman Seasonal Conditions

The good news about Grand Cayman is that there is excellent scuba diving almost every day of the year. Whenever there are high seas on one side, there is a “lee” side of the island to go diving. Visibility is usually quite good all year round. Water temperature varies with the season.
   

Summer (Jul-Sept)
Conditions are usually GREAT all around the island.

During August and early September, seas can be dead calm
for days. This is the season to dive the North Wall.
Visibility can be SPECTACULAR!!

Water is an incredible 85-87 (F) degrees.

Fall (Oct-Nov)

Best diving conditions will probably be on the
West side of Grand Cayman. North can have some calm days as well.

Occasional fall storms move the diving to the South side.

November often has better weather and diving conditions than October.
Water temp is 81-85 (F) degrees.

Winter (Dec-March)

Best diving conditions are usually on the West side of the island.

Except for the occasional “Nor'wester” storms,

seas are low chop to calm. When a storm does come,

we dive the South side (which is amazing!)

During the winter the North side seas can be

quite choppy, limiting comfortable diving.

Water temperature is usually 79-81 (F) degrees.

Spring (Apr-Jun)

Best diving conditions are usually on the West side.

There are only a few storms that affect the West side diving.

Usually calm seas. There is less chop on the North side,

so comfortable boat diving is possible as well.
Water temp is usually 82-83 (F) degrees.
