Weather in Cayman

Cayman's temperature is quite typical for that of a 'Caribbean' island. Balmy warm days that slightly cool off at night with a light breeze blowing in from the Caribbean sea. There is a definite rainy season where locals can be met with an almost clock-like predictable afternoon shower over their lunch break... so remember to pack your umbrella!

The most pleasant weather in Cayman is during the winter, from mid-November to April. During this time there is little rain, brilliant sunshine and a constant cool sea breeze. These months also coincide with peak tourist season.

May to November is the rainy season, but unless there is a tropical depression sitting over Cayman, the rain is normally only heavy for a few hours and then stops for the rest of the day. It is not uncommon to have heavy rain in one part of town while it remains dry in another.

According to Cayman’s National Weather Service, 2016 was the driest year for the country on record, whereas 2017 was the wettest in 7 years. The shifts in weather patterns may be due to global warming, which will become a major challenge for small island countries like Cayman.

Thankfully Cayman’s last major hurricane was in September 2004. Hurricane Ivan, a category five storm, caused major infrastructural damage plus took two precious lives. The Cayman Islands remains vigilant about hurricane preparedness. In this section you will also find out everything about hurricane preparedness, from where the hurricane shelters are located in Grand Cayman to what companies sell storm shutters for your home.

We also discuss the fact that Cayman lies on the boundary of the Caribbean and North American tectonic plates, in an active transform boundary zone, which means that the tectonic plates are sliding past each other. This means that the area is known for the occasional earthquake and had a recent tsunami scare in January 2018. Being prepared and having a plan is essential. Make sure your family knows what to do in the event of a major earthquake occurring in the region.

Hurricane Preparedness

A hurricane is a large rotating system of wind and water originating in the tropics with sustained surface winds of at least 74mph or more. Hurricanes can be very dangerous and Hurricane Ivan was Cayman’s last major storm in September 2004. Fortunately only two lives were lost during Ivan, but the Islands sustained a severe battering from 150 mph winds.

The hurricane season runs from the 1st of June to the 30th of November every year, so it is important to maintain a level of hurricane “readiness” if you live here. But not to worry, this section of Cayman Resident is your personal hurricane preparedness guide, from where to shelter if you live in a low lying area to what company sells solid hurricane shutters.

Earthquakes and Tsunamis in Cayman

The Cayman Islands are located close to the boundary zone of the Caribbean and North American tectonic plates. This transform boundary, where the plates slide past each other, is known to generate earthquakes. Read on for more information on what to do to prepare for, or in the event of, an earthquake and the possible resulting tsunami.

Emergency Alert System

When a threat is declared, a release is issued to all media houses to advise the public and the notification is also posted on the Hazard Management website and social media accounts.
