maritime_get_speed_profile
Retrieve historical sailing speed statistics for a route, including mean, median, and standard deviation of daily distances, with optional filtering by departure month to analyze seasonal wind patterns.
Instructions
Get historical sailing speed statistics for a route.
Returns per-segment speed profiles derived from CLIWOC ship track data, including mean, median, and standard deviation of daily distances (km/day). Optionally filtered by departure month for seasonal variation.
Args: route_id: Route identifier (e.g., "outward_outer", "return"). Use maritime_list_routes to see available routes. departure_month: Optional month (1-12) for seasonal speed data. If not provided, returns all-months aggregate. output_mode: Response format — "json" (default) or "text"
Returns: JSON or text with per-segment speed statistics
Tips for LLMs: - Compare different months to see seasonal wind patterns (e.g., monsoon effects on Indian Ocean segments) - Use with maritime_estimate_position for more informed position estimation - High std_dev indicates variable conditions on a segment - Low sample_count means less reliable statistics - The mean_km_day can help assess whether a voyage was running ahead or behind schedule
