Met Éireann will examine publishing monthly forecasts on its website in 2020, according to its head of forecasting Evelyn Cusack.
"We don't have them on our website yet, because they are more experimental, but we may well publish them in 2020, but they are just a guide really," Ms Cusack told the Irish Independent.
At the moment, "we have a reasonable confidence in a 10-day outlook", she said.
"When I started forecasting in the 1980s, it was more like one or two days.
"There has been a quiet revolution in weather forecasting in the last 50 years due to the development of supercomputers," she added.
It will be interesting to see these forecasts being released and how they verify. I foresee another project for Syran!
