Winter Honey Stores Checker
Example check (6 deep + 4 medium frames, Mid region)
Estimated stores: 76 lbs (34.5 kg)
Target for Mid-Atlantic & Midwest: 50–60 lbs.
OK — well provisioned.
Stores meet or exceed the upper target. Fit mouse guards, ensure ventilation, and check weight again by hefting in midwinter.
Method: 6 full deep frame(s) × 9 lbs + 4 full medium frame(s) × 5.5 lbs. Count partially full frames as halves.
| Region | Target stores | Full deeps equivalent |
|---|---|---|
| North (short season) | 80–90 lbs | ≈ 9–10 deep frames |
| Mid-Atlantic & Midwest | 50–60 lbs | ≈ 6–7 deep frames |
| South (long season) | 30–40 lbs | ≈ 3–4 deep frames |
Why colonies starve in late winter
Most winter losses blamed on cold are actually starvation — and it usually happens in February and March, not December. The cluster eats little in deep cold, but once the queen resumes laying in late winter, consumption triples: brood must be kept at 95°F around the clock. A hive that felt heavy at Thanksgiving can be empty by Valentine’s Day.
The second killer is position: the cluster moves up, not sideways, in cold weather. Bees can starve inches away from full frames on the outer walls. That is why late-fall arrangement matters — stores should be above and beside the cluster, not below it.
The checking calendar
- Early fall (Sep–Oct): run this checker; feed 2:1 while daytime highs stay above 50°F.
- Late fall: final weight check; fit mouse guards and ventilation.
- Midwinter (warm day >40°F): heft the hive; if light, add fondant or dry sugar directly above the cluster.
- Late winter (Feb–Mar): the danger window — check weight every 2–3 weeks until the first reliable nectar.
Frequently asked questions
How much honey does a hive need for winter?
It depends on winter length: roughly 80–90 lbs in the North (upper Midwest, New England, mountain states), 50–60 lbs in the Mid-Atlantic and Midwest, and 30–40 lbs in the South. These are colony-survival minimums recommended by university extension programs, not averages — running out in February kills more colonies than cold does.
How do I estimate stores without opening the hive?
Tilt-test or weigh: lift the back of the hive with a luggage scale, double the reading for an estimate of gross weight, then subtract equipment weight (roughly 65–75 lbs for a typical double-deep with frames and bees). In midwinter, a quick heft — if you can easily tip the hive with one hand, it is dangerously light — plus emergency sugar on top is safer than a full inspection.
How much does a full frame of honey weigh?
A fully capped deep frame holds about 8–10 lbs of honey (we use 9 lbs); a full medium frame holds 5–6 lbs (we use 5.5). Count both sides — a frame capped on only one side counts as half.
What if it is too cold to feed syrup?
Bees stop taking liquid syrup when daytime highs stay below about 50°F. After that, feed solid sugar instead: fondant, sugar bricks, or the mountain-camp method (dry granulated sugar on newspaper above the cluster). Details in the winter feeding guide.
