The Dublin Marathon weather forecast is being closely watched as 17,000 runners prepare to take on the capital this Sunday. Storms Austen and Boelo are expected to bring difficult conditions across parts of Ireland before race day, but the latest outlook suggests a calmer morning for the marathon itself.
For runners, the key message is preparation. Conditions may be manageable, but wind direction, early-morning temperatures and the long wait before the start could all influence race-day comfort and performance.
Dublin Marathon weather forecast points to calmer conditions
Event organisers say runners are currently expected to face light westerly winds and temperatures of roughly 8–12°C. The latest guidance indicates that any early rain should clear before the race gets fully under way, with relatively light winds forecast during the main running period.
Met Éireann had not issued an official race-day forecast at the time of the update, so runners should continue checking the official Dublin Marathon channels before travelling to the start line.
There has been some concern about stronger gusts, with forecasts suggesting exposed parts of the course could feel blustery. However, the wider weather picture indicates that the most disruptive rain from Storm Boelo is expected before Sunday, particularly in western and south-western counties.
How the wind could affect the Dublin Marathon course
A westerly breeze would create different challenges at various stages of the route. The opening kilometres could feel demanding, with runners facing a headwind through sections including Leeson Street, Patrick Street and Stoneybatter.
Phoenix Park is one of the more exposed parts of the course and could test runners early, particularly as the route includes a steady climb. Conditions may become more favourable around Castleknock and Chapelizod, where the wind could move behind runners and support a downhill stretch.
The middle section is likely to bring a mixture of sheltered roads, crosswinds and climbs. Runners should be prepared for:
- Headwinds on parts of the opening and central sections
- Crosswinds through exposed roads
- Helpful tailwinds around Terenure and Milltown
- A demanding climb near the course’s “Heartbreak Hill” section
- Variable wind direction approaching the finish
The final kilometres are relatively level, but a crosswind or slight headwind could make the closing stages feel longer for anyone chasing a target time.
Practical advice for runners
The Dublin Marathon weather may not be severe, but runners should plan for a cool and potentially damp morning. Organisers recommend bringing suitable layers for the wait before the race and arranging warm, dry clothing for after the finish.
A light waterproof jacket or windbreaker should provide useful protection without adding excessive weight. Runners arriving early may also consider inexpensive outer layers that can be discarded once they begin warming up.
Race storage will be available at Merrion Square and is linked to runners’ bib numbers and start waves. A change of dry clothes could make a significant difference after completing the 26.2-mile route.
Start waves and race essentials
The scheduled start times are:
- Orange Wave: 8:45am
- Green Wave: 9:05am
- Blue Wave: 9:25am
- Purple Wave: 9:45am
There will be water stations, Lucozade Sport points at miles 9.5, 13, 19 and 22, and gel stations at miles 16 and 22. Runners should still follow their own fuelling plan and avoid trying unfamiliar products on race day.

Remember the clock change
The clocks go back by one hour at 2am on Sunday morning. That gives runners an extra hour in bed, but it is still important to check alarms, travel plans and wave times in advance.
Organisers have asked participants to follow instructions from stewards and marshals throughout the event. Any significant weather-related changes will be communicated through official Dublin Marathon channels.

What to watch next
The forecast remains changeable while Storm Boelo moves through Ireland, so the final official update will be important. For now, the outlook is encouraging: cool temperatures, manageable winds and a likely break from the worst of the weekend weather.
The best approach is simple—check the forecast, arrive prepared, protect yourself from the cold before the start and follow official instructions. With the weather currently trending calmer, attention can turn back to the challenge of completing one of Ireland’s biggest sporting events.
