Ilkley Lido is set to close for the season as cooler weather approaches.
The outdoor pool will remain open for as long as possible, but will close once water temperatures drop below 10C.
Ilkley Lido said: "Wetsuits are highly recommended when the water temperature is below 15C.
"Below 12C we recommend limiting your swim to a maximum of 20 minutes.
"There’s still time to enjoy those final swims of the 2026 summer season."
The lido will host its annual Doggy Day on Saturday, October 10 and Sunday, October 11.
Each day will include three sessions, running from 9am to 10.30am, 11am to 12.30pm, and 1pm to 2.30pm.
Tickets will be available to book online from 9am on Saturday, September 26.
Entry costs £8.20 per dog, which includes one owner.
Additional tickets are priced at £4.90 for adults and £3.30 for juniors.
All tickets must be booked in advance, and guests are asked to read the full Doggy Day rules before attending.
A photographer and videographer will be present throughout both days of the event.
