Plan October around compact temperature bands and Atlantic showers
In the 2001-2025 October series, Dublin (11.2 °C, 3.3 mm/day), Cork (10.5 °C, 3.9 mm/day) and Galway (10.2 °C, 3.4 mm/day) sit within a one-degree temperature band.
Because October brings brisk Atlantic winds and shortening afternoons after the autumn equinox, start coastal drives or cliff walks early and pair every outdoor stop with a warm indoor museum, library or market alternative.
- Dublin (11.2 °C, 3.3 mm/day): slightly milder and drier mean values than the south-west and west coast points.
- Cork (10.5 °C, 3.9 mm/day) and Galway (10.2 °C, 3.4 mm/day): pack waterproof shells and waterproof footwear for exposed coastal paths.
- Finish rural driving stages before dusk and check the local weather report before heading onto headlands.

Read the local month comparison
Across the selected points, mean monthly temperature ranges from 10.2 to 11.2 °C. Mean precipitation ranges from 3.3 to 3.9 mm per day. Those ranges describe this selected point comparison, not every destination in Ireland.
Use the comparison for trip planning
- Check which named point is relevant to the stops on your actual route.
- Use mean temperature as background for planning your activities. A monthly mean includes both daytime and night-time conditions.
- Keep alternatives for weather-dependent plans and check a local forecast close to departure.
- Do not infer rain hours, rainy-day counts or severe-weather risk from millimetres per day.
