As Sweden basks in a heatwave, algal blooms in the Baltic Sea are threatening summer swims, particularly around Gotland. With temperatures soaring above 30 degrees, SMHI advises caution, urging people to stay hydrated and cool. Algal blooms, thriving in the warm, calm waters, pose a risk if ingested, especially for children and pets. Symptoms like nausea and diarrhea may occur if large amounts are swallowed. Follow safety tips to enjoy the water safely.
