marine-forecast

What This Skill Does

The marine-forecast skill provides comprehensive, real-time, and historical maritime weather data powered by Open-Meteo. It acts as a bridge between the Open-Meteo Marine and Weather APIs, aggregating complex environmental metrics into a readable format for sailing, coastal monitoring, and water-based recreational activities. By fetching data from two distinct endpoints, the agent can synthesize details regarding wave heights, swell patterns, ocean currents, and sea surface temperatures alongside critical atmospheric variables like wind speeds, gusts, air temperature, and barometric pressure. This dual-source approach ensures a complete picture of the marine environment for any location on Earth without requiring an API key.

Installation

To integrate this capability into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/alexissan/marine-forecast

Ensure that your OpenClaw agent has permissions to perform network requests, as this skill relies on external API calls to the Open-Meteo infrastructure.

Use Cases

This skill is designed for mariners, sailors, surfers, and coastal researchers. Primary use cases include:

• Pre-voyage planning to determine safe weather windows based on wave height and wind gust forecasts.
• Monitoring tidal movements and sea level changes to assist in safe navigation and port scheduling.
• Analyzing ocean currents and surface conditions for long-distance sailing routes or fishing expeditions.
• Generating daily maritime summaries for safety briefings or operational logs.

Example Prompts

1. "What is the current sea state and wind forecast for the Bay of Biscay? Use timezone Europe/Paris."
2. "Can you give me a 3-day marine forecast for the coast of Sydney, including expected swell heights and wind gusts?"
3. "Analyze the upcoming week for my boat trip leaving from Miami. What are the expected maximum wave heights and dominant wind directions?"

Tips & Limitations

• Timezone Precision: Always specify the correct IANA timezone (e.g., 'America/Los_Angeles') to ensure that hourly forecasts and daily summaries reflect local daylight variations correctly.
• Data Synthesis: Because the skill uses two APIs, look for both 'Marine' and 'Weather' responses in the output. The agent must parse these concurrently to provide a holistic briefing.
• Tide Interpretation: The tide data is provided as 'sea_level_height_msl'. To identify high and low tides, look for local peaks and troughs within the returned hourly array values.
• Offline Usage: This skill requires active internet connectivity. It cannot function in air-gapped environments.
