Goose Bone Weather Prediction: How to Read the Bone for Winter
How the goose bone winter forecast works: Martinmas and Michaelmas origins, breastbone or wishbone, how to read the colors, and how accurate it is.
Before radio forecasts, many farm families in Pennsylvania, the Midwest and Ontario had their own winter outlook hanging in the kitchen: the cleaned bone of the autumn goose, held up to the window and read for dark and light patches. This guide explains where the goose bone forecast comes from, which bone was used, how to read it and how it compares with other folk forecasts. It does not promise that a bone can beat the National Weather Service.

The goose bone forecast is an old European and American folk method of predicting winter. After a goose is eaten in autumn, traditionally at Martinmas (November 11) or Michaelmas (September 29), the cleaned breastbone or wishbone is dried and held up to the light. A mostly white or clear bone is said to mean a mild winter; dark, blue or purple patches mean cold, and the position of the dark areas shows which part of the winter will be hardest. The custom came to North America with German and British settlers and was widely quoted in rural newspapers around 1900. It is folklore, not a forecast with a proven record.
Martinmas (November 11) and Michaelmas (September 29) were traditional goose feast days in Europe.

Quick answer
The goose bone forecast is an old European and American folk method of predicting winter. After a goose is eaten in autumn, traditionally at Martinmas (November 11) or Michaelmas (September 29), the cleaned breastbone or wishbone is dried and held up to the light. A mostly white or clear bone is said to mean a mild winter; dark, blue or purple patches mean cold, and the position of the dark areas shows which part of the winter will be hardest. The custom came to North America with German and British settlers and was widely quoted in rural newspapers around 1900. It is folklore, not a forecast with a proven record.
What the goose bone forecast is
The idea is simple. A goose raised on the farm that year is killed in autumn. After the meal, one of its bones is cleaned, dried and studied. Its colors and markings are then read as a map of the coming winter, from the first frost to the thaw.
The method belongs to a large family of animal and plant signs that rural people used to guess the season ahead: the stripes of woolly bear caterpillars, the shapes inside persimmon seeds, the thickness of corn husks, the height of hornets' nests. What makes the goose bone special is that it was treated as a proper instrument, with rules, specialists and, in the late nineteenth century, local “goose bone prophets” whose predictions newspapers printed.
Martinmas, Michaelmas and the goose
The goose was the great autumn bird of Europe. Geese fattened on the stubble of harvested fields, and two feast days made them the center of the table.
Michaelmas, September 29, was the English quarter day when rents were due and the “stubble goose” was eaten. A popular legend says that Queen Elizabeth I was eating goose when news of the Spanish Armada's defeat arrived in 1588, and that she ordered goose to be eaten on that day ever after. Historians treat the story as a legend; the Michaelmas goose is older.
Martinmas, November 11, the feast of St. Martin of Tours, was the German and Central European goose day, and it still is: the Martinsgans is eaten across Germany, Austria and neighboring countries. Martinmas also marked the start of winter in the farming calendar, the time when animals came in, hired hands were paid and the winter was guessed at.
Reading the goose bone on these days was natural. The goose was the last big meal of the harvest season and the winter was the next great unknown.
How the tradition came to America
German-speaking settlers brought the Martinmas goose and its bone to Pennsylvania, and British and Irish settlers brought the Michaelmas version. By the nineteenth century the goose bone forecast was known across the farming Northeast and Midwest and in Ontario.
Around 1900 it had its moment of fame. Small-town newspapers in the United States and Canada regularly quoted a local goose bone prophet on the winter to come; the Napanee Beaver in Ontario mentioned one in February 1901. In the same years the young United States Weather Bureau, founded as a civilian agency in 1890, was building a scientific forecasting network, and newspapers enjoyed setting the old prophet against the new bureau.
The tradition never disappeared. Almanac writers still describe it every autumn, and families with a goose on the table sometimes keep up the custom as a kind of seasonal game. It sits alongside other American forecasts such as the woolly bear caterpillar and the persimmon seed.
Breastbone or wishbone?
Sources disagree on which bone is meant, and it is worth knowing both versions.
The breastbone. Older European and Irish accounts, and many Pennsylvania German ones, describe the breastbone or keel, the broad, thin plate of bone under the breast meat. Held against the light, it is partly translucent, and its dark and light areas are easy to see.
The wishbone. Some modern American writers, including the Old Farmer's Almanac, describe reading the wishbone, the forked bone at the base of the neck, the same bone that is pulled for a wish at Thanksgiving. Our article on the wishbone tradition tells that story.
Both versions agree on the essentials: the bird must be a young goose hatched that year, it should be farm-raised rather than bought, and the bone is read after cooking and drying.
Why a goose, and why this year's bird?
The logic of the custom is that a young goose has lived through exactly one summer and fall, and its body has “stored” what the season was preparing for. A bird from the store, raised indoors and far away, has nothing to say about your local winter.
Some almanac writers add a folk explanation for the dark color: that a dark bone shows a bird that laid down extra oil against the cold. It is a tidy story, but there is no study behind it.
How to read a goose bone
The reading rules vary from family to family, but the main pattern is consistent:
White, clear or translucent bone: a mild or “open” winter with little snow.
Dark, blue, purple or black patches: cold weather. The darker and larger, the harder the winter.
Mottled or spotted bone: changeable weather, with cold spells and thaws.
A thick bone: in some Irish and British accounts, a thick bone means thick weather: a long, heavy winter.
Where the dark areas sit: the bone is read from one end to the other as the months of winter. On the breastbone, the front end is usually read as early winter and the back as late winter; on the wishbone, dark tips are read as a cold spring. Dark color near the front with a clear back means a hard start and an early spring, and the reverse means a late, cold end.
Readers usually wait until the bone is fully dried, often a few days on a shelf, because a fresh bone looks darker than it is.
Temple Tip
Photograph the bone against a window on the day you read it and write your forecast beside the picture, with the date. In spring, compare it with what actually happened. After three or four winters you will have your own small record, and a much better feel for why forecasters love data.
Goose bone, persimmon seed, woolly bear: folk forecasts compared
Three American folk forecasts compared
| Sign | When it is read | What is read | Mild winter | Hard winter |
|---|---|---|---|---|
| Goose bone | After the autumn goose, Michaelmas to Martinmas or Thanksgiving | Color and pattern of the dried bone | White, clear | Dark, blue, purple patches |
| Persimmon seed | When the fruit ripens in fall | Shape inside the split seed | Fork | Spoon (heavy snow), knife (icy, cutting wind) |
| Woolly bear caterpillar | When they cross roads in fall | Width of the brown band | Wide brown band | Mostly black |
All three work the same way: a small natural sign is read as a picture of the season. All three are also the kind of forecast that people remember when it comes true and forget when it does not. Reading bones for other purposes, such as knucklebone casting, is far older still.
Does it work? The weather record
No controlled study has shown that the color of a goose bone predicts winter weather. Bone color depends on the bird's age, breed, diet and blood content, and on how the bone is cooked, cleaned and dried. None of these has a known link to the weather months ahead.
Modern seasonal forecasts rest on ocean temperatures, patterns such as El Niño and La Niña, and computer models, and even they give only probabilities for a whole winter. A single bone cannot carry that information.
That does not make the custom pointless. Like other folk forecasts, it was a way of paying close attention to the season, sharing guesses around the table and bracing for winter together. That social side is what still makes it fun.
Quiz: which winter oracle suits you?
Three questions to find the folk forecast that fits your fall.
Voices from practice
People who grew up on farms with a goose at Martinmas or Thanksgiving often remember the bone on the windowsill more clearly than the forecast itself, and say that reading it was a job given to the children.
Folk forecast enthusiasts frequently report that the fun lies in keeping score: writing down the bone's verdict and checking it against the real winter in March, with mixed results that they share good-humoredly.
Practitioners who follow the wheel of the year often describe the autumn goose, Martinmas and the first frost as a natural point to pause and set intentions for the dark half of the year.
What we don't promise
We do not promise that a goose bone, or any other folk sign, will tell you what the winter will bring. For planning travel, heating, farming or anything that matters, use official forecasts from the National Weather Service and its Climate Prediction Center.
What the goose bone offers is a living piece of European and American folk history, a reason to look closely at the season and a small ritual to share. Enjoy it for that.
Practically: how to work with this
- Choose your bird. Tradition calls for a young goose raised that year. If you cook a turkey or duck instead, treat the reading as play, not as the traditional method.
- Save the bone. After the meal, remove the breastbone or the wishbone and clean off meat and fat.
- Dry it. Leave it on a shelf or windowsill for several days until it is completely dry.
- Read it against the light. Hold it up to a bright window. Note white and dark areas and read the bone from front to back as early, mid and late winter.
- Record it. Photograph the bone and write down your forecast and the date.
- Check in spring. Compare the forecast with the winter you actually had. Keep the notes for next year.

Frequently asked questions
How do you predict winter with a goose bone?
Dry the breastbone or wishbone of an autumn goose and hold it to the light. White or clear means a mild winter, dark or purple patches mean cold, and the position of the dark areas shows which months will be hardest.
Which bone is used, the breastbone or the wishbone?
Older European and Pennsylvania German accounts use the breastbone. Some modern almanacs describe the wishbone. Both are read the same way.
When is the goose bone read?
After the autumn goose is eaten, traditionally at Michaelmas (September 29) or Martinmas (November 11), and in America often at Thanksgiving.
Can I use a turkey bone?
Tradition calls for a young, farm-raised goose. A turkey bone can be read for fun, but that is a modern variation.
Is the goose bone forecast accurate?
No study has shown that it predicts winter weather. It is folklore, best enjoyed as a seasonal custom.
Where does the goose bone forecast come from?
From European goose customs at Michaelmas and Martinmas. German and British settlers brought it to North America, where it was popular around 1900.
