The average high usually is during the day, and the average low usually is during the night. Seawater temperatures hover about midway between those high and low air temperatures. So they are comfortable and sometimes balmy for swimmers during June.

Grand Cayman’s average high in June of 92 degrees Fahrenheit or 33 Celsius is typical for the island from May through November. By comparison, temperatures during the day average in the low to mid 80s Fahrenheit in the winter.

It may be hot in June, but the rainfall is a risk.

Cayman Rainfall

The island averages about six inches of rain historically during the month. Like the temperatures, June rainfall for Grand Cayman is among the highest in the Caribbean.

June is the second month of the annual rainy season for Grand Cayman that begins in May and goes through November. The rainy season is part of the Caribbean hurricane season.

In contrast, the dry season is January through April when average rainfall is less than two inches a month. This dry season is the best and most popular time to visit the island for cruises.

The dry season has about 10 days with rain each month. June averages 16.

Vacationers who can travel only during the summer because of jobs or kids in school will find that June or July are better than August for the risk of rain.

Total rainfall and the number of days with rain begins climbing in August until reaching the high point of the year in September and October. Rainfall then averages about eight inches a month.
