Bermuda’s weather climate is sub-tropical, mild in the winter, spring, and autumn (fall), but from late May to October, it can be uncomfortably hot and with especially high humidity. The hottest part of the year is from May through mid-October, when temperatures hover between 75°F / 23°C and 85°F / 29°C. Humidity, often well over 85%, is at its highest from July through mid-October.
Bermuda weather conditions can be tricky to plan for, so it’s important to know what to wear and pack for your trip. During the winter months, from November through April, temperatures range from 55°F / 13°C to 70°F / 21°C, making a light coat or sweater necessary in the early morning and evening. Shorts and T-shirts will suffice during the day. In the hotter months, it’s best to wear light-colored, breathable clothing and keep a small umbrella on hand since Bermuda is known for its sudden showers. A bathing suit should be packed regardless of when you’re visiting, as the beaches are never too far away.
When the temperatures start to rise during the spring and summer, it’s best to wear light and breathable fabrics, such as cotton. It’s also good to invest in a wide-brimmed hat or sun visor to protect your skin from the sun. For evenings out, Bermuda shorts and a nice top are suitable attire for both men and women. For colder months, bring along a light jacket or a raincoat in case of occasional showers. Be sure to also pack sandals for the beach and a pair of comfortable shoes for sightseeing and walking around.
Rain is also a factor to consider when visiting Bermuda. The island gets an average of 49 inches of rain each year, with the most rain occurring in late spring and early summer (May and June). In the event of a storm, it is advised to dress for the conditions and seek shelter indoors. Also, keep in mind that Bermuda is prone to hurricanes from August to November, so it is important to stay informed of any potential weather warnings that may be issued.
Despite its latitude and longitude – and its location so far north of the Caribbean, nearly a thousand miles north of it in fact – Bermuda is entirely frost-free, snow-free, and ice-free. Why? Because the warm waters of the Gulf Stream pass near Bermuda.
However, it can be favorable to hay fever sufferers. Ragweed does not exist in Bermuda, and pollens of other weeds are quickly blown out to sea. But note that for those with allergies., the always humid climate breeds mold, mildew, and mites. Some pharmaceuticals available without prescription elsewhere require prescriptions in Bermuda from registered local medical doctors. There are helpful pharmacies located across the island.
Bermuda’s ocean winds are tempered by the Gulf Stream, but when south winds prevail, the humidity rises, and sometimes thunderstorms occur. The highest humidity months are July and August. Temperatures rarely drop below 55 degrees F or exceed 90 degrees F. The lowest air temperature ever recorded was 43.6F. The highest was 94F. Water temperatures during winter months are much the same as the air temperature, ranging from about 66F (in January) through 75F until the late spring.
Enough annual rainfall is one reason why Bermuda is usually lush in foliage and greenery despite its very shallow alkali soil. There is no monsoon or rainy season because Bermuda is not in the Caribbean, but some months tend to be wetter than others. But others can be devoid of much rain. Also, several – like late June, July, and August in particular, and early September – can be extremely (and unpleasantly) humid. If this affects you badly, and you don’t mind cooler water for swimming, then try May or June or late September to October. The temperate weather is perfect for enjoying outdoor activities across the island.
