Monthly weather and packing notes
October makes a weather-resistant jacket useful again. Put longer walks earlier in the day and save an indoor stop for a rainy afternoon. In Dublin, plan one outfit for Trinity and the Liffey bridges, carry rain protection for Dublin Castle’s courtyards, and use removable layers inside the Kildare Street archaeology museum.
- Daytime
- 12–16°C
- Evenings
- 5–9°C
- Rain
- Showers possible
- Daylight
- Daylight is shortening: do the outdoor route before indoor stops.
- Packing style
- Removable layers and a waterproof outer jacket
Planning bands are the rounded 1991–2020 Dublin Airport mean daily maximum (13.6°C) and minimum (7.1°C), plus or minus 2°C. These bands are clothing prompts, not forecast limits or statistical confidence intervals. Airport averages are a nearby station proxy, not street-level city measurements. Liffey bridges feel more exposed in wind. Rainfall is 78.4 mm in an average month, with 11.6 days of at least 1 mm. Check the forecast for your own dates.
