Body Surfing in La Jolla

Winter has arrived in force here in New England and we're planning our April vacation trip to distract us from the cold outside. We're avid body surfers and wondered if Boomer Beach in late April will be built up enough for body surfing. What can we expect in terms of water temps at that time of year? We're obviously used to swimming in pretty cold water up here but we spend most of summers body surfing on eastern Long Island where the waters are bit warmer so anything close to 70 degrees is warm for us. Thanks
