There has been quite a bit of attention in the media recently about the warm sea temperatures around the coast. Below see the plots for L4 and E1, updated with the most recent data. It shows that there is much more variability at L4 due to the strong effects of the tides. At E1 the temperatures are close to the maximum ever recorded (1908, 1976 and 1983 seem to be ahead at the moment).
