Interstadial of the Devensian cold stage which occurred c 13,000-11,000 bp. It consisted of a rapid temperature rise to an initial thermal maximum, followed by a slight temperature decline at 12,000 bp. It stabilized until 11,000 bp, when it fell sharply at the start of the Loch Lomond Stadial. The Windermere interstadial may be correlated with Godwin's Pollen Zone II.
