Bermuda Rain – No Rainy Season

There is no rainy season as such in Bermuda. Rainfall is distributed fairly evenly throughout the year and averages 5 inches per month.

Showers tend to be short, heavy, and often unexpected. Most locals (and those in the know) carry raincoats, even on sunny days. If you’re travelling by scooter a coat should be one of the essential items stored under your seat. Cheap poncho-style coats can be purchased throughout the island. Pharmacies are a good place to buy them. Locals tend to carry more expensive rain gear, usually a full rain suit with jacket and trousers.

It’s highly unlikely that your vacation will be completely ruined by rain. Constant rainfall over a number of days is relatively rare. The Bermuda Weather Service has detailed historical rainfall statistics on their website. Choose any month from the past and you can see how much rain fell each day. It’s quite common to see the majority of a month’s rain fall on just a handful of days in the month, with the rest of the days being dry or almost dry.

In summary, don’t consider the rain when planning the timing of your vacation. Rainy periods cannot be predicted so far in advance.

Rain Water Harvesting – How houses get their supply of water

Spend any time in Bermuda and you’ll almost certainly notice that all the roofs are white. They’re one of the signature features of the island’s architecture. Although very pretty, they’re not that way for aesthetic reasons and serve a distinct purpose.

There are no rivers or streams in Bermuda. Most houses depend on rainwater as their main source of fresh water. In fact, it’s the law that almost all buildings need to have a roof that can catch water and a means of storing it. 80 percent of the roof area needs to be guttered and the storage tank needs to have a capacity of at least one hundred gallons for every 10 square feet of catchment area.

Until modern times, roofs were built with limestone slates, quarried on the island. More recent buildings use other materials such as concrete slates or extruded polystyrene panels.

In a traditional roof, the slates supported on a timber frame and bedded in a cement mortar. The roofs slopes at an angle, not so high that water spills over the gutter, but not so low to collapse under its own weight. It was lime wash, giving the roof its characteristic white colour.

Around 70 percent of the water used in the island’s households comes from roofs. The remainder comes from private wells, water trucks, and the mains. Approximately 65 percent of residences do not have direct access to supplementary water (the mains or a private well) and rely on water trucks in times of need.
