Met Éireann has advised that a "prolonged spell of very warm to hot weather" is set to hit the country this week and last into next week.
The national meteorological service this afternoon (Monday, July 6) said that a spike in temperatures is likely to deliver "heatwave conditions".
According to Met Éireann day time temperatures could "exceed" 25° and possibly climb "to the high 20s or even low 30s in places".
"The UV Index is expected to be high to very high," it added.
Hot day time temperatures will give way to "warm and humid nights" according to the national meteorological service with an average of 15° or higher expected.
It added: "Possible tropical nights may occur in places this weekend.
"There is also the chance of some thunderstorms later this week".
Farmers have been urged to be aware of the potential "animal welfare issues" that hot weather can create.
Livestock should always be checked more frequently in hot weather, according to the Department of Agriculture, Food and the Marine (DAFM).
It has also advised that owners should try to avoid transporting animals during the hottest parts of the day.
Animals at higher risk of heat stress include young, dark-coloured or pregnant animals; animals recovering from illness; pigs; and high-producing dairy cows.
Signs of heat stress include: faster breathing or panting; loss of appetite; increased water intake; drooling; and listlessness or lethargy. In severe cases, animals may become unconscious.
DAFM advises that the number of watering points and water flow may need to be increased during hot weather as demand increases.
Drinking points should be checked more often during hot weather to ensure they are working and that water pressure is adequate.
Stock should also be monitored for signs of problems with water supply such as queuing or crowding at water points.
According to Met Éireann the hot weather this week and next could also lead to "drought" in some areas and it has advised of other potential impacts including wildfires and forest fires.
