Ireland Dublin Weather in March — Climate Guide
March in Dublin is high
March is high for Dublin.
March is dominated by St Patrick's Day (March 17) — the year's biggest event. The multi-day St Patrick's Festival brings a massive parade, packed pubs, street performances, and a wave of international visitors, with hotel prices at a peak and the whole city sold out around the date.
If the festival is what you want, it's an unforgettable, joyous (and very crowded) few days — book months ahead. If it isn't, avoid mid-March for a calmer, cheaper visit.

Dublin in March — Full Picture
March is dominated by St Patrick's Day (March 17) — the year's biggest event. The multi-day St Patrick's Festival brings a massive parade, packed pubs, street performances, and a wave of international visitors, with hotel prices at a peak and the whole city sold out around the date.
If the festival is what you want, it's an unforgettable, joyous (and very crowded) few days — book months ahead. If it isn't, avoid mid-March for a calmer, cheaper visit.
The weather is early-spring changeable: around 10°C/4°C, cool with frequent showers and a noticeable day-night swing, but daffodils appear and the parks brighten. When the clocks go forward in late March, evenings suddenly get long.
Outside the festival window, March is a decent shoulder month — improving light, spring in the air, and (St Patrick's aside) reasonable crowds.
Note: layers and a waterproof are essential; spring weather flips quickly. Book very early if you're coming for St Patrick's Day.
What to Wear & What to Pack
Early spring — around 10°C/4°C, cool with a big day-night swing. A waterproof jacket, sweater or fleece, and layers, plus waterproof shoes. Days reach ~12h by month's end; weather is changeable.
