About stormglass.io

stormglass.io is a powerful weather API service with global coverage, proudly developed in Sweden since 2018. Our core mission is to solve the complex weather data puzzle for developers worldwide.

The Problem with Weather Data

The weather data landscape is fragmented. You have a vast ocean of providers—some relying on proprietary satellites, others on in-house modeling, and still others focusing on niche regions. Every single provider claims superior accuracy. As a product developer, choosing the right one for your application is a complex task.

That’s where stormglass.io steps in. We act as your intelligent layer, eliminating the need to manage multiple contracts or compare raw data feeds. We identify the best weather forecast data from multiple world-leading providers based on their performance, and deliver it to you through a unified, fast, and highly developer-friendly API.

With stormglass.io, you gain confidence and control. You can be certain that the data empowering your product is not just accurate, but the best available for any given location and time. Plus, we give you full, transparent insight into the performance of every single underlying data provider, allowing you to see and compare the raw sources directly within our platform.
