Guardamar calm sea

All the time we have visited Guardamar we have found in the summer the sea can be fairly choppy and rough, with very few calm days, since we have been here in the autumn and winter months the sea has been relatively calm on most days, and some times there has barely been a wave lapping on the beach. Surprisingly completely the other way round to the summer, this winter the weather is unbelievably good with fine warm days and little rain, so I wonder if this is the normal pattern.
