Who has the most accurate weather forecast? ›

IBM's The Weather Company Continues to Be the World's Most Accurate Forecaster Overall, Despite Growing Competition and Amid Weather's Increased Impact. - The Weather Company was over 3 times more likely to be the most accurate forecaster than other weather providers studied.

The solid line is for the Northern Hemisphere, and the dashed line is for the Southern. Three-day forecasts — shown in blue — have been pretty accurate since the 1980s, and have still gotten a lot better over time. Today the accuracy is around 97%.

The Short Answer:

A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

IBM and its subsidiary The Weather Company continue to be the overall most accurate weather forecast providers worldwide, according to a new study. The Weather Company includes weather.com and other digital properties of The Weather Channel.

Weather Channel would be the most accurate. For a period of fifty-eight days, data was collected from all three companies regarding temperature, humidity, and wind speed.

The "Probability of Precipitation" (PoP) simply describes the probability that the forecast grid/point in question will receive at least 0.01" of rain. So, in this example, there is a 40 percent probability for at least 0.01" of rain at the specific forecast point of interest!

If the weather service is projecting a 50% chance of rain, that means that for the forecast area, about half of the area might expect to see some rain. It doesn't mean that it will rain half the day. That means that you might not get any rain at all, but other areas of the region may get rain.

Closer look at percentages

Let's use 60% as the rain chance in the forecast. That means 60% of the entire area (Central Florida) could see measurable rain at some point in the day, while the other 40% won't.

AccuWeather/ABC weathercasts are the most accurate overall, in every market, with a percentage average of 14.1% greater accuracy than CBS, 18% greater accuracy than NBC and 20.4% greater accuracy than FOX.

Global recognition as a world-leading National Met Service

Striving for forecast accuracy is in our DNA. Our global Numerical Weather Prediction (NWP) model, the foundation of our accurate weather provision, is verified using standards defined by the World Meteorological Organisation (WMO).

AccuWeather gathers the best and most comprehensive weather data to deliver forecasts with Superior Accuracy. Forecasts are pinpointed for every location on Earth and extend further ahead than any other source.

Weather apps are generally accurate for simple forecasts over the next few days; their accuracy can decrease when hazardous weather is expected.

Powered by proprietary GRAF technology (Global High-Resolution Atmospheric Forecasting), The Weather Company is The World's Most Accurate Forecaster¹ and a trusted weather partner for people and businesses everywhere.

Short-range weather forecasts are considerably more accurate than long-range forecasts. In fact, according to the National Oceanic and Atmospheric Administration (NOAA), a five-day forecast is accurate about 80% of the time. A one-day temperature forecast is typically accurate within 2.5 degrees.

NWP is widely recognized as the most accurate method for weather forecasting, utilizing complex mathematical algorithms to simulate atmospheric behavior.
