Is there good scuba diving in Barcelona?

Barcelona is full of rocky coral reefs full of life: barracudas, moray eels, groupers. The protected area includes Posidonia oceanica meadows, one of the largest on the Catalan coast, with its associated fauna and the incredible beauty that it represents. The dives are simple and adapted to all levels, from beginners to more experienced. At depths ranging from 5 to 40m Common marine life sightings for Barcelona Winter: Minimum temperature 13ºC, crystal clear waters as long as there are no storms. It is the best time to enjoy life associated with the rock as the algae are in decline. Seeing dolphins is relatively easy Spring: Temperature 18ºC minimum, the algae begin their boom with the heat. It is the time of the sunfish and many nudibranchs in "flirting" Summer: Temperature 26ºC, calm waters, the mornings more than the afternoons, but always incredible once you put your head under the water... At the beginning of summer the parsnips are full and at the end of the eagles. Autumn: Temperature 21ºC, somewhat more unpredictable weather, but eagles, dentex, groupers, lobsters, moray eels... are celebrating! Book your diving Barcelona

I doubt there is good diving from Barcelona, although it looks like some outfits offer it. I know the Medes Islands from L'Estartit - about 2 hrs North, is thought of as the best diving in the Costa Brava. Tossa de Mar also has diving. I dove the Cap de Creus from Roses, further up the coast. Nice diving, not comparable to the Caribbean or other tropical diving, but enjoyable. About 70 F water at the surface in Sept - maybe colder at depth. The Medes are the best place to dive on the Costa Brava. L'Escala is also a nice place to dive. Anyway, I think it's worth the challenge. You'll find great Diving Spots arround Illes Medes or Cap de Creus. But it is a 1.5 hr drive north of Barcelona.
