Nõva Beach is generally considered safe for swimming, especially during the warmer months. The sandy bottom and relatively shallow waters near the shore make it suitable for families. However, as with any natural beach, it's always advisable to be aware of local conditions, potential currents, and to supervise children closely. There are typically no lifeguards on duty, so personal responsibility is key.

The best time to visit Nõva Beach for good weather is typically during the summer months, from June to August, when temperatures are warmest and daylight hours are longest. For budget travel, visiting just outside the peak summer season, such as late May or early September, can offer pleasant weather with potentially lower accommodation costs and fewer crowds. The shoulder seasons still provide opportunities for enjoying the beach's natural beauty.
