The last five Julys explain your next energy bill better than any forecast will.
Forecasts answer one question: what will the atmosphere do next. Most operational decisions need to answer a second question, what does the atmosphere usually do here, and how much does it vary. Only historical data can answer that.
A forecast tells you Thursday will hit 96 degrees. Historical data tells you whether that's a normal July afternoon or a once-a-decade event, how often it happens, and what it did to your energy load the last five times it did. Baselines, return periods, model validation, and demand correlation all come from the observational record. The forecast is the last step in that chain, not a substitute for it.
Whether you're leveraging historical precipitation data to power a smart irrigation system, predicting future energy consumption for a rooftop HVAC unit, or analyzing the effectiveness of your emergency response crews during a severe weather event, your challenges are similar to others. That's where the historical endpoints of our weather API come in, allowing you to turn data into intelligence.

7-day rainfall totals from Hurricane Harvey, generated using the Xweather API and Raster Maps.
Xweather raster maps
Xweather Raster Maps is a highly customizable tile mapping platform that allows you to visualize weather in high-definition, with the option to extend back to the last 30 days. Adding historical weather to your mapping application clarifies the weather story, making patterns and trends more obvious, relevant, and actionable.

Historic radar and satellite layers for Australia.
In a world of simplistic weather applications, historical analysis adds context, perspective, and the hyper-relevant data streams you need to see what you've been missing. We'll probably never be able to cool a warm front or adjust the tempo of the wind, rain, or snow, but tapping the full power of historical weather enhances data analytics and reduces risk.
Let the Xweather team explain how embracing the past can drive future success.
