A weather warning is in place for small boats on waters along all Irish coasts due to powerful northwesterly winds, according to Met Éireann.
The yellow warning (the lowest of the three warning categories) says wind speeds will reach force six for a period of time this morning.
These winds have brought a sudden end to summer with temperatures today, and for the remainder of the week, approximately 3 degrees below the average for this time of year.
While it will be a bright, fresh, breezy day, with sunny spells and scattered showers, temperatures will be between 14 to 18 degrees.
Temperatures for August generally average between 17 and 21 degrees.
According to Met Eireann the northwesterly direction of the wind is bringing colder air from the North Atlantic over the country.
The current cold snap is expected to last for most of this week before temperatures rise again over the weekend.
However, unfortunately, the warm settled weather that marked much of July and early August is unlikely to return this month.
