Dublin in October: what to plant
Over the last 5 years, October in Dublin has run 10.0–14.8°C with about 120 mm of rain across the month. Here is what weather like that will carry to harvest.
Everything above is a five-year average. In the game it is this — the weather Dublin is actually having, today.
Grow one in Dublin's weather right now →❄️ No sub-zero nights in October in the last 5 years — frost is not the limiting factor here.
🗓️ This month sits inside the frost-free window. Average last spring frost around Feb 10, first autumn frost around Nov 30 — roughly 294 frost-free days. Sow tender crops after the last frost date and make sure they finish before the first.
☀️ About 5.9 h of sunshine a day this month. Within the month it cools by about 2.1°C from the first ten days to the last — the window for autumn sowings is opening.
Sow this month — when would you harvest?
Assuming you sow in mid-October, then adding up the warmth Dublin usually gets, one day at a time — which is why some of these run past the end of the month.
| Crop | Days | Harvest around |
|---|---|---|
| 🥬 Napa cabbage | 216 | May 18 |
| 🥦 Broccoli | 202 | May 4 |
| 🌿 Parsley | 202 | May 4 |
| 🫘 Broad bean | 184 | Apr 16 |
| ⚪ Turnip | 158 | Mar 21 |
| 🧄 Garlic | 143 | Mar 6 |
⏳ Too late this month: Strawberry, Bok Choy, Daikon radish, Peas, Beetroot, Marigold would still be in the ground when the first frost arrives (around Nov 30). Sow them earlier in the year, or grow them under cover.
🌡️ Cucumber, Tomato, Chili Pepper, Pumpkin, Edamame, Yardlong bean, Bitter melon, Luffa, Winter melon, Aubergine, Okra never accumulate enough heat outdoors in Dublin — not in any month. Locally these need a greenhouse or a warm windowsill.
