Introduction

---

Anguilla has a tropical climate, hot all year round, with a slightly cooler period from December to March and a hotter, muggy period from May to October. Luckily, sea breezes are able to relieve a bit the heat of the day.
Rainfall is generally not very abundant, since it amounts to around 1,000 millimeters (40 inches) per year.
As normally happens in tropical areas, the rains usually fall in the form of downpours or thunderstorms, in days when the sun shines for a few hours anyway. More rarely, there can be heavy and prolonged rains, when tropical depressions and hurricanes hit the islands (see below).
Anguilla is located in the northernmost part of the Lesser Antilles, and it's a British overseas territory, formed by the main island, where the capital is found, plus some small coral islands.

Hurricanes

---

From June to November, in Anguilla as in the whole area of the West Indies, there is the danger of tropical storms and hurricanes, with greater probability from August to October.

When to go

---

The best time to visit Anguilla runs from December to April, a period when the temperatures are a bit lower and outside of the hurricane season, and particularly the months of February and March, which are the driest ones.
In summer, in June and July, it usually rains a bit less than in August, and there is also a lower probability of hurricanes.

What to pack

---

From December to April: bring light clothing, and a light sweater or sweatshirt for the evening and for the breeze.
From May to November: bring lightweight, loose-fitting clothing, and possibly a light sweatshirt and a light raincoat for thunderstorms.
When going to the reef, you can bring snorkeling equipment, including water shoes or rubber-soled shoes.
