About
Stormglass is a professional weather data API service that provides developers and businesses with direct access to accurate, high-resolution global weather forecasts and historical datasets. Leveraging AI weather models, the platform aggregates and delivers data across a comprehensive set of parameters — including air temperature, wind, precipitation, humidity, soil moisture, wave height, swell, water temperature, salinity, UV index, cloud cover, and tidal extremes, among many others. The API is designed for seamless integration into a wide variety of applications. Marine and maritime companies use it for vessel routing, autonomous ship navigation, and fuel optimization. Renewable energy operators rely on it for wind and solar power forecasting. AgTech platforms integrate it for crop and soil intelligence. Consumer apps use it for end-user weather experiences. The API also supports fishing, aquaculture, and ocean research workflows. Stormglass offers a freemium pricing model with a free tier (10 requests/day) for testing, and scalable paid plans starting at €19/month for up to 500 requests/day, going up to €129/month for 25,000 requests/day, with custom enterprise plans also available. All plans include access to the full suite of weather parameters. The platform is trusted by leading companies such as Roke, Hefring Marine, VPS, Fishidy, Ankeri, and Buffalo Automation. Its combination of data breadth, accuracy, and developer simplicity makes it a go-to solution for weather-dependent industries.
Key Features
- Comprehensive Weather Parameters: Access 20+ atmospheric parameters (temperature, wind, precipitation, humidity, soil moisture) and 20+ marine parameters (wave height, swell, water temperature, salinity, pH, oxygen) through a single API.
- AI-Powered Weather Models: Forecasts are generated using AI weather models, delivering higher accuracy and resolution than traditional meteorological services.
- Historical Weather Data: Query past weather records globally for backtesting, research, analytics, and training machine learning models.
- Tide & Solar Data: Includes tidal extremes (high/low sea level), solar radiation, UV index, and cloud cover — essential for marine, energy, and agricultural applications.
- Flexible, Scalable Pricing: From a free development tier to enterprise custom plans, Stormglass scales with your usage needs, with optional annual discounts on paid plans.
Use Cases
- Marine companies integrating real-time wave, wind, and current data into vessel routing and autonomous ship navigation platforms.
- Renewable energy operators forecasting wind and solar power output to optimize grid management and energy production.
- AgTech platforms using soil moisture, temperature, and precipitation data to deliver precision farming insights to growers.
- Consumer weather app developers accessing high-resolution forecast data including UV index, visibility, and tidal information.
- Researchers and data scientists querying historical weather datasets to backtest models or study long-term climate patterns.
Pros
- Wide Parameter Coverage: One API covers atmospheric, marine, tidal, solar, and soil data — eliminating the need to integrate multiple weather data providers.
- Free Tier for Testing: Developers can sign up for free and immediately start testing with 10 requests/day, reducing friction for evaluation and prototyping.
- Proven Enterprise Reliability: Trusted by established companies in maritime, renewable energy, and AgTech sectors, indicating strong data quality and uptime reliability.
- Simple REST API Integration: Well-documented API makes integration straightforward, reducing development time for teams building weather-dependent features.
Cons
- Free Tier Is Very Limited: Only 10 requests per day on the free tier, which may be insufficient for meaningful development or testing beyond basic exploration.
- No Support on Lower-Tier Plans: Free and Small plans come without customer support, which can be challenging for developers who encounter integration issues.
- Cost Scales Quickly for High-Volume Use: At €129/month for 25,000 requests/day, high-volume applications may need to negotiate custom enterprise plans, adding procurement complexity.
Frequently Asked Questions
What types of weather data does Stormglass provide?
Stormglass provides atmospheric data (temperature, pressure, wind, precipitation, humidity, visibility, soil moisture), marine data (waves, swell, water temperature, salinity, pH, oxygen, chlorophyll), tidal data (high/low extremes, sea level), and solar/UV data — all accessible through a single REST API.
Is there a free plan available?
Yes. Stormglass offers a free tier at €0/month that allows 10 API requests per day with access to all weather parameters. It is not intended for commercial use and does not include customer support.
