The water at Wylies Baths has stayed reasonably warm since Winter officially began about three weeks ago. I swam there on both Saturday and Sunday this past weekend, just a couple of days before the solstice. Both days were bright and sunny, but, due to a swell, I had to save the lap swimming until low tide at 4PM or thereabouts. By this time, the sun was low in the sky, the pool was in shadow and there was a bit of a chill in the air.
On Saturday the water temperature was 19°C, and on Sunday it was 18°C, so still warm (although there was an occasional wetsuit to be seen). There's still no real need for a swim cap, but I will admit that I was glad of a hot shower and a mug of tea on Sunday.
I swam twenty sparkling lengths on Saturday (plus another couple without the goggles, just looking at the views), then another fifteen on Sunday. There were plenty of fishes swimming around the pool, but I didn't see the friendly octopus this weekend. The resident cormorant also failed to show up.
