Met Eireann's forecast for the month of May shows little hope for summer weather

Bank Holiday Monday is off to a rough start with a rain and wind warning in place for 11 counties.

And unfortunately it looks as though that could be a sign of things to come with poor weather expected all throughout May.

According to Met Eireann the heavy rain will arrive this week bringing a risk of flooding and onshores gales.

Meanwhile the rain will die down a week later but there is a risk of frost throughout the night as temperatures plummet once again.

Thankfully it looks as though things may pick up towards the end of the month with a bit more sun, however it seems that rain will be a common feature throughout the month.

Here's the full forecast for the month of May:

Week 1 (Monday May 3 to Sunday May 9)

There’s a strong signal for unsettled conditions over the week, with an active low pressure system moving across Ireland on Monday with a cold and unstable northwesterly airflow establishing in its clearance. With a zonal jet positioned south of Ireland, there is the chance of further depressions feeding in from the Atlantic later in the week.

Temperatures will be below average and rainfall amounts above average for the time of year throughout the country. The main hazards will be rainfall on Monday with potential onshore gales bringing a risk of spot flooding. Late season frosts are likely during some of the nights and there’s the potential for thunderstorm activity.

Week 2 (Monday May 10 to Sunday May 16)

A more settled picture is signalled for Week 2 with high pressure dominating in a mainly light to moderate west to northwest airflow. Still signals though for below average temperatures but likely to be closer to average than in Week 1. Rainfall amounts are expected to be below average for much of the country but more normal amounts in northern areas due to shower activity. The main hazards would be a slight risk of further frosts at night and possible fog forming at night in the slack airflow.

Week 3 (Monday May 17 to Sunday May 23)

Week 3 shows a weaker signal for high pressure to the southwest feeding in a northwesterly airflow but temperatures returning to around average for the time of year. Showers will likely be a feature with northwestern areas likely to see above average rainfall with drier than average conditions likely further to the southeast. No significant hazards are indicated at present.

Week 4 (Monday May 24 to Sunday May 30)

Week 4 shows a signal for more unsettled conditions with a mainly southwesterly airflow. Rain and showers will likely feed in from the Atlantic at times with western and southwestern areas possibly receiving above average rainfall. Temperatures will likely be around average for much of the country. In this setup, the most likely hazards would be wind and rain.
