The Chief Medical Officer is appealing to people to continue obeying the Covid-19 restrictions, despite the good weather.
Temperatures could reach up to 20 degrees today, leading to fears people will start travelling to beauty spots like parks and beaches.
A further 44 people with the virus have died, bringing the death toll to 730, while there are now 16,040 confirmed cases.
Dr. Tony Holohan says he's noticing an increase in people out and about in recent days.
"We've seen anecdotal reports of that, and in my own experience yes, I agree.
"Warm weather understandably brings people out, and we understand that given the nature of the arrangements that are in place it is difficult for people, it its challenging, and those temptations are easy to understand.
"We don't want any complacency - we want us to keep going with the measures, we have further progress to make with this epidemic."
