George Town observes a rather interesting precipitation pattern. Although drier and wetter periods can be distinguished, the total amount of precipitation throughout the year remains relatively low. Snow, given the tropical climate of the Cayman Islands, does not fall here; all precipitation comes as rain.

The driest period falls on the months from January to April. At this time, only about 1 mm of precipitation falls monthly. Despite such a small amount, January can have up to 11 days with precipitation, which indicates very light and possibly short-lived rains. By April, the number of rainy days drops to 6, making this month one of the driest not only in volume but also in frequency of precipitation.

From May to November, the amount of precipitation and rainy days increases, forming a wetter season, albeit without extreme downpours. The peak falls on October, which is the wettest month of the year: about 7 mm of precipitation falls, and the number of rainy days reaches 21. Also, relatively high precipitation and rainy days are observed in June (about 4 mm of precipitation and 14 rainy days), September (about 4 mm of precipitation and 18 rainy days), and November (about 5 mm of precipitation and 17 rainy days). Even in these months, rains are most likely to be light or moderate short spells rather than prolonged tropical downpours, given the overall low volume of precipitation.

Overall, even in the so-called "wet season" in George Town, rains are not a serious obstacle to a holiday. They most often refresh the air and are quickly replaced by the sun. December is also relatively dry, with 2 mm of precipitation and about 13 rainy days, serving as a transition to the drier start of the year.

When packing your suitcase for a trip to George Town, remember that a warm tropical climate awaits you all year round, often accompanied by a pleasant sea breeze. Average annual temperatures range from 25°C to 29°C, so the basis of your wardrobe should be light, breathable fabrics: cotton T-shirts, linen shirts, shorts, skirts, and sundresses. Be sure to take swimwear, as the Cayman Islands are famous for their magnificent beaches. Don't forget high SPF sunscreen, headwear (a hat or cap), and quality sunglasses to protect against the bright tropical sun. Comfortable shoes, such as sandals or light sneakers, are perfect for walking around the city and the coast.

Although the weather in George Town is generally very comfortable, it is worth considering small seasonal features related to precipitation. The drier period lasts from January to April, when rains are rare. From May to November, and especially in October, the number of days with precipitation increases, although the rains themselves are most often short-lived and not very strong, given the overall low volume of precipitation. For this period, it would be useful to bring a light folding umbrella or a compact raincoat. Also, in case of evening coolness from the sea breeze or for visiting places with air conditioning, a light cardigan, thin sweater, or long-sleeved shirt will come in handy. And, of course, do not forget insect repellent, especially if you plan evening walks in the fresh air.
