Grand Cayman weather in November usually rains enough to discourage people from visiting this popular western Caribbean island.

Grand Cayman, the largest island of the Cayman Islands, attracts cruise visitors in part because of its convenient location and in part because of major attractions such as Stingray City and Seven Mile Beach.

The majority of visitors come from cruises. But cruise traffic drops from September through October for the simple reason that weather then is quite bad historically. The weather isn’t much better in November.

The following statistics come from 30-year averages from the Cayman Islands National Weather Service. They will vary somewhat from year to year. But they follow a pattern that makes it easier to predict the actual weather.

November Rainfall

Total rainfall for Grand Cayman in November averages more than 6.5 inches, according to the Cayman Islands National Weather Service. This compares to the eight inches or more the island receives in September and October.

It also rains an average of 17 days during November, which is higher than the average for other Caribbean destinations this time month.

At least it isn’t as bad as the 19 days in October and the 20 days in September.

November Temperatures

Keeping warm during the day isn’t a problem. The average high temperature in Grand Cayman during November is 90 degrees Fahrenheit or 32 Celsius, according to the Cayman Islands National Weather Service.

The average low is a bit cool at 70 degrees Farhenheit or 21 Celsius, which bring seawater temperatures down a bit.

But that’s Grand Cayman. It has one of the highest spreads between high and low temperatures in the Caribbean in November with days quite warm and nights quite cool by comparison.

Whether to Go

As someone who has traveled in the Caribbean in November, I can say that it is a risky month to go for most destinations in the region.

Grand Cayman is even riskier than most because of its higher than normal total rain and rain days.

The best reason to go to the Caribbean in November is that total tourism is usually quite a bit lower and discounts somewhat higher.

In the case of Grand Cayman, fewer cruises are available because of the weather and lower popularity.

But that doesn’t stop some people from going by air to spend a week on the island for the great attractions it offers—as long as it doesn’t rain.
