With its unique weather character and archipelago structure the weather in Los Roques is the most stable and inviting in the Antilles and a well known refugee for yachters seeking sun and shelter.
The principle feature of the Los Roques archipelago is an imposing coral reef that extends across a good 24 km on the eastern side of the archipelago, and which provides natural protection against the trade winds regularly blowing from the east. The frequent hurricanes characteristic of the Caribbean never arrive in Los Roques thanks to this natural shield.
The Los Roques archipelago has a windy climate with trade winds blowing from the east and often reaching velocities of 12 knots. The average air temperature, virtually stable the entire year, is 28°C while the water temperature varies from 29°C at the surface to 25°C in the deeper water. Rainfall is scarce, significantly less than in the rest of the Caribbean, as clouds are always swept away by the winds. Average yearly rainfall is 250 mm. Whilst on the continent summer is the rainy season, in Los Roques it hardly ever rains – thanks to an unusual atmospheric phenomenon, any bad weather clears up before it arrives as far as Los Roques.
