Fishing season reports

How these reports are built

Every number on a report page comes from one frozen weather snapshot: daily maximum and mean temperature, mean sea-level pressure, wind, precipitation and weather code for each location, covering 2024-09-01 to 2026-08-31 — 2 full years, 730 days per location. The snapshot is fetched once from the Open-Meteo historical archive and committed to the repository, so a report recomputes to the same table every time and nobody has to take our word for a figure. The index itself is the same code path as the daily pages; the only difference is that the report scores days that already happened, so its trend factors read what the weather actually did rather than what it was forecast to do.

Reports are recomputed when the snapshot is re-fetched, not on a schedule — a report is a statement about a fixed window of weather, and the window is printed on the page.

Using these numbers

The index rates how favourable the weather and water conditions are for lure fishing — it is a planning signal, not a catch guarantee and not a statement about where fish are. A high-scoring month means more days with the conditions that usually fish well, not that any given day will. Local regulations, water levels, access and closures all sit outside the model; check them before you travel. See the river reading guide for what to do once you are on the bank, or the where to cast tool for picking a spot.
