After a wet summer, T-shirt weather arrives in October. It’s the kind of balmy end-of-season Saturday afternoon that seaside ice-cream vendors surely must pray for. The clifftop car parks are filling up fast. People are drawn to this stretch of coastline to breathe clean, salty air along the promenade, play on the beach, enjoy a spot of sea angling or appreciate panoramic sea views that stretch from Tyneside in the north to Cleveland’s cliffs in the south. We’ve watched dolphins along this shore recently, but today there are none, only an inquisitive grey seal, surfacing close inshore. Sea glass collectors on Blast beach – heads down, searching for treasure – don’t notice the watcher, who vanishes in a swirl of sparkling wavelets.
