It's Monday, September 14th, 2026. If you're looking out the window this morning, you might be seeing a bit of a mixed bag. For many of us, especially in the north and east, it's starting off dry with some decent sunny spells. But don't get too comfortable, because the weather across Ireland is set to shift quite a bit as the day progresses. We're looking at rain and drizzle making its way across the country, turning heavy in places.

Let's break down what to expect from Ireland's weather today, and what the rest of the week has in store for us.

This Morning: A Brief Reprieve

If you're in Ulster or Leinster, you've likely woken up to a relatively pleasant start. There are some nice sunny spells breaking through, making for a decent morning commute or a quick walk before the day gets going. However, this is just the calm before the storm, so to speak.

Down in the south and west, things are already a bit different. Outbreaks of rain and drizzle have started to develop, and these are going to be on the move. So, if you're in counties like Kerry, Cork, or Galway, you're already feeling the first touches of what's coming for the rest of us.

Afternoon and Evening: Rain Takes Hold

As we head into the afternoon and evening, that rain which started in the south and west will extend eastwards across the entire island. Met Éireann is telling us it's going to become "heavy and persistent at times." That sounds like a good reason to make sure you have your umbrella handy, even if you started the day under clear skies.

Along with the rain, we're also going to see mist and hill fog forming. This is pretty typical for this time of year, as the temperatures start to cool and moisture hangs in the air. If you're driving, especially on higher ground, be aware that visibility could be reduced.

Now, for the temperatures. Despite the incoming rain, it's not going to be a cold day. Highest temperatures are expected to range from 17 to 24 degrees. The warmest spots will definitely be in the east, which makes sense given the rain is coming from the west. So, if you're in Dublin, you might still get a bit of warmth before the heavier rain arrives. We'll have moderate southwesterly breezes throughout the day, which won't do much to shift that rain quickly.

Tonight: Clearing Up, But Still Showery

As Monday night rolls in, the outbreaks of rain will gradually clear eastwards. This is good news, but it won't be a completely dry night for everyone. Following the main band of rain, we'll see a mix of scattered showers and clear spells. So, if you're heading out, don't assume the rain is completely gone for good.

Mist patches will also be forming again overnight. Temperatures will drop to between 11 and 14 degrees, which is a fairly mild September night. The moderate southwesterly winds will ease and become westerly as the rain clears.

Looking Ahead: Tuesday and Beyond

Tuesday, September 15th, is shaping up to be a brighter day overall. We can expect a mix of sunny spells and scattered showers, which will spread from the northwest. It will definitely feel fresher, with highest temperatures ranging from 14 to 18 degrees. Light to moderate northwesterly breezes will be present, feeling a bit brisker on the coast.

The national outlook from Met Éireann suggests a changeable week ahead. This isn't exactly surprising for Ireland in mid-September, is it? We're always in for a bit of everything.

Tuesday Night: Scattered showers will become mainly confined to the north and west. Elsewhere, there might be isolated showers. Lowest temperatures will be between 9 and 13 degrees, with light to moderate westerly breezes.

Wednesday: The middle of the week brings a mix of well-scattered showers and sunny spells in the morning. Many areas will remain dry for a good portion of the day. However, cloud will start to build in the west during the afternoon, bringing patches of drizzle. Highest temperatures will be around 15 to 17 degrees, with a light to moderate westerly breeze.

Wednesday Night: Expect a cloudy night with outbreaks of rain and drizzle moving eastwards across the country. This rain will eventually clear to scattered showers. Lowest temperatures are forecast to be between 9 and 12 degrees, with moderate southwesterly winds.

Thursday: Thursday will see sunny spells and scattered showers. It's expected to become blustery at times, with moderate to fresh and gusty westerly winds. There's a possibility of cloudier conditions and more persistent rain, particularly in the north. Highest temperatures will be 14 to 17 degrees.

Friday: We might get a dry start to Friday with some possible sunny spells. However, rain is expected to develop through the day. Highest temperatures will be 14 to 18 degrees, with mostly moderate southwesterly breezes.

The weekend outlook suggests things will remain quite changeable, with further rain and showers on the cards. But, and this is important, there will also be dry and bright periods. So, it's not all doom and gloom. Daytime temperatures are expected to stay in the mid to high teens.
