Leverage our Historical Weather API for a Variety of Use Cases

Insurance: Validate Claims, Prepare for Future Events, and Reduce Fraud

Sports and Entertainment: Optimize Sales During Specific Conditions

During sporting events, customers are more likely to purchase specific products based on outdoor weather. For example, the Patriots football team used weather forecasting to make opportunistic product sales and increase revenue by up to 20% on certain days.

Uber uses minute-by-minute weather data to optimize offers during weather events, reduce the cost of customer acquisitions by 20%, and improve estimated time of arrival (ETA) accuracy by 25%.

Aviation: Analyze Past Delays, Cancellations, and Understaffing

The travel industry could arguably use past weather data the most, and JetBlue is one such trendsetter leveraging the Tomorrow.io historical weather API to save $50,000 per month in operational costs due to severe weather.

Energy and Utility: Make Predictions for Staffing and Costs During Outages

In 2020, India saw one of the biggest storms ever recorded, which put 300,000 residents at risk. IndiGrid used predictive analytics from historical weather data to determine staffing and support for future severe weather events that could cause damage and outages.
