30 Day Weather Forecast May 2021 for Ireland

 May will be a cold month with unsettled spells and also quite breezy at times so no sign of Summer just yet. Things may warm up as we head towards the later part of the month. Temperatures are going to be about 3c BELOW normal over the course of the month rarely going above 15c.

Rainfall will be well up to normal even slightly above. Sunshine will be in short supply after the bright weather from April it will feel like we have gone backwards in season weather wise.

June has early indications of some much warmer weather but it remains to be seen how this actually pans out.

Warm and Unsettled

The weather remains changeable for the next 30 days with a lot more in the way of rain or showers but also some warm sunshine too as temperatures for August will continue to be above expectations. A cool and unsettled August was predicted here at weathergossip but the position of the Low pressure to the West of Irelands Shore has ensured that warmer Southerlies are streaming up over us. This will continue to be the case until the last week of August when some cooler weather may start to push in once again. Strangely despite all the rain August could well turn out to be the warmest in 6 years in some places.

Warm to start then Thundery

warm this end to May for Ireland

Warm weather looks likely to start the period with temperatures getting up to the mid 20s in some parts of Ireland but then they will drop back to the High teens around the start of June. Thereafter it will be quite thundery but warm and there will be heavy rain especially in more Southern and Eastern parts of Ireland. The North and the West may see more in the way of sunshine for the first week of June. Temperatures for June will be higher than they have been all year and the month will certainly have an overall average temperature of above average. In the normal run of things in June we would get temperatures during the day of between 15 and 18c but this year it looks like the temperature will be around 16 to 20c a lot of the time and in any prolonged sunshine even higher. A lot of the weather in the next 30 days in Ireland is going to come from the South and East of the country so more of a continental feel to the weather even when it is wet but at the moment the first week of the period is looking very nice indeed and if you were to pinpoint the best periods of weather it would seem that May 23rd to May 27th will see a lot of warm sunny weather for Ireland and also June 7th to June 10th looks good at the moment.
