Frost Dates in South East England
early to mid May
late October to November
The growing season here
The South East is often comparatively warm, bright and dry, giving a generous season for vegetables, fruit and flowers. However, clear spring nights can bring sharp frost to inland hollows and rural plots. These periods are broad regional averages, not promises: coastal influence, altitude, walls, aspect and local frost pockets all alter the real season.
What it means for sowing & planting out
Sow hardy crops outdoors through spring as conditions allow, and raise tender vegetables under cover for planting later. Wait until the local danger of frost has passed before setting out tomatoes, peppers, squash, French beans or tender annuals, usually after a careful hardening-off period. Inland gardens should be especially wary of cold nights in May. Check the Met Office forecast before planting.
Tips
Dry spells are often as important as frost here, so mulch beds and water newly planted crops deeply. Use walls, fences and urban shelter to create warmer spots, but do not assume they remove frost risk. Ask the RHS or a local garden centre about reliable timings for your district.
These are approximate regional averages - frost varies with altitude, frost pockets, coast and aspect. Check the Met Office forecast for your area before acting. Page updated 19 Sep 2026.
