Teenagers on their long summer holidays cool off on a hot summer afternoon by jumping into the clear sea off the wooden jetty dock pier at Aberystwyth on the west wales coast . The weather is set to improve even more tomorrow, culminating in a mini-heatwave, with temperatures forecast to reach the high 20s or low 30s centigrade in parts of the UK.
