Keep free-form notes about the plan, conditions, decisions, good days, and tough days. Fishing Diary is separate from Catch Logs, so you can capture the whole trip even when there is no catch to log, while giving pattern analysis better trip context later.

Catch Logs are for caught fish, photos, species, and catch-specific conditions. Fishing Diary is for private observations, trip plans, hunches, missed bites, weather notes, and lessons you want to find again later.
Write the details that do not fit a catch record: what you tried, what changed, and what you want to remember next time.
Capture context from both productive and slow trips, including the trips where no catch log was created.
Saved embedding vectors help Fish Fathom group related diary notes and catch logs by meaning, then compare those patterns by season and conditions.
The dedicated AI Fishing Pattern Analysis page explains how Fish Fathom compares catch logs and Fishing Diary entries in a semantic 3D view. Diary notes matter because they preserve plans, observations, missed bites, and lessons that a catch-only record cannot capture.
Explore AI Fishing Pattern AnalysisWhen a diary entry has trip time and area context, Fish Fathom can attach a trip-time weather snapshot from the nearest station so later searches and recommendations can compare your notes against the conditions you actually saw.
Wind speed in knots for the trip window.
Wave height and wave period for the closest available marine observation.
Air temperature and water temperature when those readings are available.
Barometric pressure in hPa for pressure-pattern comparisons.
Current speed plus tide direction to preserve movement context.
Moon phase and solunar score for timing patterns across diary entries.
Nearest station, observation time, source, and confidence score are kept with the snapshot so the context stays traceable.
