In some cases, such as at Athenry, County Galway and Claremorris, County Mayo weather stations recorded 18.6C and 18.2C respectively which are both 2C higher than previous maximums.
The highest so far this year is 19.2C in Dublin's Phoenix Park but the record still stands as 20.1C in November 2015 at Dooks, County Kerry.
Minimum temperatures have been high too this year with 14.6C at Valentia, County Kerry observed, the third highest on record for the month in Ireland.
In the image, Ballycotton Island Lighthouse in County Cork on a warm, cloudy November day. This lighthouse was painted black in 1902 to distinguish it from the nearby Capel Island Lighthouse.
The forecast is for cooler conditions this week, for a few days, but with a return to warmer weather by next weekend.
It is a difficult photograph to shoot a landscape like this contre-jour but the movement and colour in the sky, coupled with some good post-processing has resulted in a fine image that is in contrast to shooting with the sun and its clear light (image coming soon in a subsequent post).

Sheep Island rises some 30 metres above the North Atlantic with mostly sheer cliffs, a thin layer of soil on top gives a green colour particularly in spring. In centuries past, local farmers would graze sheep out here being able to land only on the calmest of days.
Some doubt that landing a vessel here with sheep is possible, but on a calm day and good local knowledge this would be a difficult, but not impossible, task.
Sheep Island is home to a large proportion of Ireland's population of the northern European sub-species of cormorant and is a protected habitat.
You can just see the coast of Scotland, faintly on the horizon under the grey cloud to the right of Sheep Island in this image.
