In the Salmon section, we publish graphs of river levels on the major rivers, which are updated daily (twice daily in season). They show how the levels have moved at various points on the river for the last 24 hours, the last month and the year so far. You can register to receive the river heights by SMS text message each day you are fishing (for a small charge to the river management).
In the same section, there are also weekly reports on what the prospects are for the following week and you can register to receive these by email each week (no charge).
Both salmon fishing and sea fishing are also affected by the tides, with their varying heights and timings, and again the serious fisher will wish to keep an eye on these too. Fortunately, predicting tides is a whole lot easier, and much more reliable, than predicting the weather!
The Admiralty EasyTide site gives free predictions for 7 days or you can register to get predictions further ahead. You can also go direct to relevant pages for these ports that are near our major rivers:
