Cayman Islands Climate - Hire A Car

The Cayman Islands lie in the far Western Caribbean, closer to the equator then a lot of people realise, between latitudes 19° and 20° North. The islands are cooled by prevailing trade winds, but the sun is HOT and we advise always to wear sunscreen, a shady hat and sunglasses. Please take the sun in small doses to avoid sunburn.

 

As a guide, the following outlines our range of temperature through winter and summer.

What to Wear


Visitors should remember that the Cayman Islands remains a "proper" British Crown Colony and our people are conservative by nature. The Cayman Islands Government strictly prohibits all forms of public nudity, so please do not wear bathing suits or scanty beach wear beyond the beach or cruise ship - and cover up when in public areas. As we say in Cayman, Please keep your shell on!

 

Neat, casual and comfortable tropical attire are appropriate throughout the Cayman Islands. Visitors will want to bring smart casual wear for evenings out at our restaurants. When attending church services, "Sunday dress" is appropriate - shorts and T-shirts are not considered acceptable, especially for ladies. However, ties are not expected!
