About Maritime Weather API
Datalastic Sea Weather API delivers a complete and accurate look at weather conditions for a vessel, port, or geographic location.
Instead of combining separate marine and general weather services, the endpoint merges marine conditions and atmospheric conditions for the same position and time window.
You can use the API to build voyage-planning tools, vessel-monitoring platforms, port applications, operational dashboards, maritime risk systems, fleet-management software, and other weather-sensitive marine applications.
Flexible Location Resolution
The Maritime Weather API lets you request weather using the location information you already have. You can query by geographic coordinates, retrieve weather at a vessel’s latest known position using its MMSI, IMO, or UUID, or request conditions for a port using its UN/LOCODE or Datalastic port UUID.
Regardless of which method you choose, the API returns the same consistent response format, making it easy to integrate weather data into existing maritime applications without additional conversion logic.
Current Conditions and 7-Day Forecasts
Get the weather picture you need from a single endpoint, from conditions right now to forecasts for the week ahead. The Maritime Weather API provides current conditions together with 7-day hourly and daily forecasts, and multiple modes can be requested at once. This makes it easy to use the same endpoint for real-time monitoring, short-term operational decisions, and longer-term voyage planning.
Maritime Weather for AI Agents
Datalastic Maritime Weather Data is also available through our MCP server, allowing AI assistants and agents to retrieve maritime weather data directly using natural language.
Connect your AI agent to Datalastic MCP to access current weather conditions and 7-day forecasts for vessels, ports, and geographic locations.
Ask questions about weather conditions and let your AI agent handle the interaction with Datalastic MCP. Incorporate sea weather data into your operational workflows, research, voyage planning, and more.
