Forecasting Technology

Developed over 22 years with 200,000+ man hours and 100,000+ hours of computer time, and generating forecasts for 6.4 million locations in all 195 countries and islands,  a forecast Weather Trends issued one year ago is more accurate than every other weather company’s 5-14 day forecast.

  • 75% of the automated forecasting process is math-based using a combination of Gaussian Theory, Periodicity, Climate Cycles and Statistics that automatically cycle through a multi-variable 300-step decision tree of if/then scenarios to generate year-ahead by day or week with high/low temperature and weekly rain/snow forecasts by location everywhere in the world. 100% automated algorithms perform quadrillions of calculations on a Rackspace cloud-dedicated infrastructure using 5.3 million lines of code.
  • 20% of the process uses a blend of 8 traditional meteorological atmospheric and oceanic time series (PDO, SOI, QBO, AMO, etc.) to refine the initial year-ahead numerical forecast.
  • 4% is an automated location specific correction process to adjust for trend volatility biases, topographic factors and 10 to 30 year climate trend adjustments.
  • 1% is human QC from Weather Trend’s degreed meteorologists/climatologists and PhD from Rutgers University, Millersville, Penn State, Plymouth State University, and the University of Miami.

Most Accurate & Granular Approach To Long-Range Global Weather Forecasting

80%+ Accuracy

Independently audited verifying industry-leading accuracy for both short and year-ahead forecasts; 80%+ accuracy on year-ahead temperature and precipitation forecasts.  A forecast Weather Trends issued one year ago is more accurate than every other weather company’s 5 to 14-day forecasts.



1-14 Day Forecasting

14 global animated weather maps integrated with wt360’s Google Map API tracking temperature, precipitation (rain, ice and snow), wind speed/direction, satellite, lightning, UV index, sun hours, humidity, pressure, wave heights/direction, ocean temperature, earthquakes, US severe weather warnings and US radar.  Complete global coverage in two mapping formats: 6 global (spherical) views and Google Map view.
