Forecasting the weather is science, and despite weather forecasters getting it wrong sometimes, meteorology is always a valid process to predict weather. Satellite technology like Polar-orbiting satellites is programmed to process weather patterns and provide data. An analysis results in a weather forecast. However, it is undeniable how weather can be unpredictable at times, resulting in forecasts going wrong. Regardless of the weather bashing, Almanacs since ancient times have got it right most of the time. Take the Old Farmer’s Almanac, for instance. This is a tool revered by farmers and gardeners for over 232 years, so what’s their secret?
A Legacy of Weather Prediction
The Old Farmer’s Almanac, America’s oldest weather forecaster, has been predicting long-range weather since 1792. Founded by Robert B. Thomas, the periodical was originally a tool for farmers and gardeners to plan. Today, it is a journal respected by all interested in the weather-from outdoor enthusiasts, travelers, and economists to truckers, shippers, and skywatchers—and everyone in between.
The Secret Formula
The Old Farmer’s Almanac says since its inception, they have relied on a secret formula developed by Thomas. The formula, improved over time, now incorporates solar science, climatology, and meteorology. It has been refined with modern technology and data to yield weather predictions trusted by meteorologists worldwide.
Solar Science
One of the key components of the Almanac’s formula is the study of sunspots and solar activity. Solar science helps forecast weather patterns by examining how solar cycles impact the Earth’s atmosphere. Sunspots, areas of intense magnetic activity on the sun, affect solar radiation levels, which in turn influence atmospheric conditions and weather patterns. For instance, variations in solar radiation can alter jet streams and pressure systems, leading to changes in global weather. By analyzing historical sunspot cycles and their correlation with past weather, meteorologists can make informed predictions about future conditions, aiding in long-range forecasts like those in the Old Farmer’s Almanac.
Climatology and Meteorology
The Almanac uses climatology to compare current weather trends with historical data, considering changes in climate over time. This historical perspective allows the Almanac to make educated predictions about future weather.
Traditional meteorology also plays a role in the Almanac’s predictions. By studying atmospheric conditions, the Almanac can provide forecasts that account for various weather phenomena, such as jet streams and oscillations.
What is Normal Weather according to the Farmer’s Almanac
The Old Farmer’s Almanac writes on its website, “The weather predictions in our almanac (and any other forecast for that matter) compare temperature and precipitation levels to “normal.” Our forecasts consider normal to be the 30-year average.”
The National Center for Environmental Information updates the U.S. normal temperatures every ten years using new 30-year averages. In 2023, The Old Farmer’s Almanac based its long-range predictions on the period from 1991 to 2020, replacing the previous data set from 1981 to 2010.
Accuracy and Tradition
How accurate is the Old Farmer’s Almanac is a good question. A University of Illinois study said the Almanac was only about 52 per cent accurate. Several other websites have also agreed, yet the Almanac remains a prominent contributing element concerning U.S. weather.
Despite the reliance on a secret formula, the Almanac acknowledges that predicting weather with complete accuracy is impossible. However, they claim an accuracy rate of around 80%, making their forecasts a trusted resource for many.
How Climate Change Impacts the Almanac’s Forecast
Climate change is factored into the Almanac’s predictions. The warming trends and shifting weather patterns are considered, particularly when adjusting temperature predictions for polar and temperate regions. According to the Almanac, winters aren’t as cold as they were 50 years ago. Though the U.S. does see months of extreme cold, it is relatively fewer consecutive periods of temperatures 6 degrees below average.
Climate Signals and Teleconnections
According to the Almanac, climate signals known as teleconnections are used to make long-range weather forecasts. These connections between weather phenomena across different parts of the Earth, like El Niño and La Niña, influence climate patterns over vast distances. However, due to climate change, teleconnections can evolve and may not be as reliable as in the past. The Almanac continuously monitors these signals to assess their effectiveness while also watching for the development of new teleconnections over time.
What About Weather Lore?
Some might think the Almanac’s long-range forecasts are based on folklore. According to weather lore, signs like abundant acorns, thick corn husks, or tough apple skins suggest a harsh winter, while low bees’ nests and thin onion skins hint at a milder one. Even a persimmon seed or the behavior of rabbits might offer clues!
Although the Almanac neither confirms nor denies the reliability of such folklore, it acknowledges that centuries ago, people observed these phenomena and noticed corresponding weather patterns. Therefore, the Almanac concedes there might be some truth to these beliefs. However, folklore does not play a role in crafting the weather forecasts in the annual Almanac.
Current Fall Weather Trends
The Almanac forecasts a mixed bag for the current fall season across the United States, with some regions experiencing prolonged warm weather while others face early cold snaps. The lingering effects of summer may persist in the northeast and mid-Atlantic. Fall, which begins on Sunday, September 22, 2024, is seeing a variety of forecasts across weather channels with a consensus on matching the Almanac’s forecast of a slightly warmer fall in most parts of the U.S. This includes colder temperatures in the northern regions and milder conditions in the south, with significant precipitation fluctuations.
Winter 2024-2025 Outlook
The winter of 2024-2025 is expected to bring varied conditions across the U.S. Northern states may experience a more traditional winter, with the potential for significant snowfall, while southern states might see a milder, wetter season. The influence of climate change will likely result in more intense and unpredictable weather patterns.
It is interesting to note that The Old Farmer’s Almanac is now in its 232nd year and remains a bestseller in the United States and Canada. It has been in circulation since George Washington was President, making it the longest-running periodical in the country.
