How does it work?

Spire’s weather forecasts are unique because of our proprietary radio occultation data. Our satellites can measure temperature, pressure and humidity over 10,000 times per day worldwide. Continuous scan of the atmosphere creates a unique unbiased global weather observation dataset.

"The Spire Weather Forecast excels for open ocean weather forecast accuracy. The level of development and speed of innovation that Spire is putting into its models continues to impress us."
