The lake’s climate in the winter months is extremely cold and inhospitable and throughout the year the lake’s temperature rarely gets above 15 degrees C. Most travellers come here in summer, when the nights are a little warmer. At this time the lake feels fairly hot, despite the cooling winds that breeze from the lake that are refreshing, bringing moisture and birds off the lake’s surface. For ornithologists, the optimum time to visit is also between March and June, when the birds are in breeding and so flock here in large numbers.

August and September are also a good time to visit, mainly for the scenery around the lake, as the oil-seed rape bursts into sunbeam yellow blossom and contrasts with the salty blue of the lake beyond.
