Weather & Climate

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 coral friendly sunscreen, a shady hat and sunglasses. Please take the sun in small doses to avoid sunburn. Nothing ruins a great dive vacation quicker than a bad sunburn.
