Kendwa is about 3 km from Nungwi, an easy walk along the beach during low tide, but impossible at high tide. The only option is a schlepp along back roads, hard going on the rocky roads, or a boat trip at a steep $20 per trip. One could perhaps walk to Nungwi at low tide and take the sunset cruise from there and ask to be dropped off at Kendwa.
The 2 km connecting road from the main route to the north was re-graded in 2007, and while still rough, is not nearly as bad as before. There is little difference here between high and low tides so swimming is possible any time of day. There may be some cloud and wind and quick rainshowers in June/July but the sun is usually out and the weather very pleasant. The beach is fine white sand or ground shells, the water turquoise blue, the sunsets spectacular and the local boat activity picturesque.
