Most beach restaurants at Salobreña do not open until Easter and the coastal strip can look pretty dismal when everywhere is shut up. The village has bars open all year though for local residents.
March is ´iffy´ weatherwise - you could be lucky and get very pleasant days with temperatures well into the 60s - starts going very cool from 3 p,m. onwards - but you should also expect some very heavy showers and strong winds.
We like Salobreña but, personally, think it is a better place to stay from Spring to Autumn rather than over the Winter months.
For more beach front life / restaurants in March look at neighbouring Almuñecar or, for even more places, Nerja.
