Weather is an often-overlooked factor when it comes to many businesses, especially for those not directly interested in it. Yet a poor understanding of weather, from misunderstanding rainfall to not anticipating a massive snowfall, can be costly regardless of your company size and industry.

In the U.S. alone, weather accounts for more than $600 billion a year in lost revenue. That is certainly not a number that should be overlooked.

So how can you avoid having the weather inadvertently cost your company its time and money?

Combining years of research and analysis, weather data providers now offer a lookback at historical weather patterns, which can offer potential solutions and predict future weather occurrences to give companies an edge against nature herself. This can help with understanding and preparation.

We’ve compiled a list of the top 7 historical weather data providers on the Datarade platform to help you start your search for a provider that is right for you.
