Concerns over a sewage leak at a UK beach were dispelled when the water turned a murky brown hue, later confirmed to be caused by algae by Natural Resources Wales [NRW]. The discolouration at Porthdinllaen beach in Gwynedd prompted worries from swimmers during the Bank Holiday weekend. Despite initial pollution fears at this remote Welsh coast location overlooking the Irish Sea, NRW’s Arfon Hughes reassured the public that the discoloration was due to non-toxic algae called Phaeocystis, a common occurrence in coastal waters forming harmless brown scum affected by sunlight and warmer temperatures.
North Wales Live highlighted Porthdinllaen’s picturesque sandy bay sheltered by a headland, renowned for its iconic beach pub, Ty Coch, recognized among the world’s top beach bars. The beach experienced high traffic over the Bank Holiday weekend, coinciding with UK temperatures exceeding 34C. While Heathrow Airport and Kew Gardens in London registered as the warmest spots, the weather forecast predicts thunderstorms in parts of the Midlands, Home Counties, and northern England, with potential flooding, lightning strikes, hail, or strong winds.
