Dumfries and Galloway catches the full Atlantic, which keeps autumns long and mild. The first autumn frost holds off to late October.
The surprise is spring: Dumfries records more April air frost than Edinburgh or Inverness, so despite its mild reputation it is not Scotland’s earliest region. Mild in autumn, ordinary in spring.

Frost dates for Dumfries & Galloway
- Lowland (Solway coast; under ~150m): last frost late April, first autumn frost late October, safe to plant out mid May.
- Upland (Southern Uplands; above ~150m): last frost mid-to-late May, first autumn frost late September, safe to plant out early June.
Dates are rounded to the nearest half month, from named Met Office stations (1991-2020 averages). Lowland means under about 150m; upland is above that.
| Garden | Last spring frost | First autumn frost | Safe to plant out | Season | Station | Confidence |
|---|---|---|---|---|---|---|
| lowland | late April | late October | mid May | ~180 days | Dumfries, Crichton Royal No 2 | high |
| upland | mid-to-late May | late September | early June | ~130 days | Eskdalemuir (242m) | high |
What this means for growing here
Sow and plant out to these dates rather than a UK calendar, and remember they are regional averages. Your own plot can run two to four weeks later in a frost pocket, or earlier against a warm wall. If your garden is above about 150m, use the upland figures; below that, the lowland ones. The Planting Calendar turns these into a month-by-month plan.
When to plant out tender crops here
Frost-tender crops go outside only once the safe planting-out date has passed, about two weeks after the last frost: mid May on low ground and the coast, early June on high ground in Dumfries & Galloway. That applies to tomatoes, basil, cucumbers, sweetcorn, peppers, chillies and aubergines grown outdoors. That date is the earliest they can go out, not a promise they will ripen: on high ground only about 130 frost-free days follow it, so a greenhouse, polytunnel or cloches are the safer bet there.
