Conditions on this page are recalculated from the latest forecast every time it is opened, for the current date in the location's own time zone.
A warm, overcast day with a light 8–15 km/h (5–9 mph) breeze and a barometer that has been falling slowly for the last 6–12 hours is as good as it gets. Overcast light keeps fish shallow all day, the breeze breaks up the surface so they cannot see you, and a slowly dropping barometer triggers feeding ahead of a weather change. Add water temperature inside the species' active band and you have a prime-bite day. Before, in almost every case. The hours ahead of a front — falling pressure, thickening cloud, rising humidity — are the strongest feeding window of the week. After the rain passes, pressure rises fast and the classic post-frontal shutdown begins; it typically takes 24–48 hours for fish to feed normally again. The exception is rivers: a spate after heavy rain pushes migratory fish such as salmon and sea trout upstream and can be outstanding once the water starts dropping and clearing. They bite, but they move. Bright, high-pressure bluebird days push fish deeper, tighter to cover and into shade lines. Fish structure edges, drop-offs, overhanging trees and current seams, downsize your presentation, and concentrate on dawn and dusk. Grayling and mackerel are notable exceptions that genuinely fish well on bright days. A light chop is one of the most underrated advantages an angler can get. At 8–15 km/h (5–9 mph) the broken surface hides your silhouette and pushes plankton, then baitfish, then predators against the windward bank — so fish the shore the wind is blowing into, not the comfortable sheltered one. Above roughly 35 km/h (22 mph), casting accuracy and safety collapse and the score drops sharply. Because everything that makes a day unpleasant for people makes it comfortable for fish. Grey light removes their fear of predators from above, a chop hides your line and silhouette, drizzle washes food into the margins, and a falling barometer tells them harder weather is coming and it is time to eat. The lakeside car park is also empty. The days most people photograph — blue sky, flat calm, high pressure — are the days the fish are hardest to fool. Cover water with something that searches: an inline spinner, a spinnerbait or a natural-pattern crankbait at mid depth, retrieved at medium pace with irregular pauses. Under heavy cloud go dark and solid so the lure shows a clear silhouette; in bright, clear conditions go smaller and more natural. Fish the windward bank if there is any breeze at all. The Bite Score tool above prints a specific lure, colour, retrieve and location for whatever conditions you set. The trend matters far more than the absolute number. A slow fall from around 1020 hPa toward 1005 hPa over 6–12 hours is the single most reliable "go now" signal in freshwater fishing. Steady pressure over two or more days produces consistent if unspectacular sport. Rapidly rising pressure behind a departed front is the worst signature of all. Fish sense pressure change through the swim bladder and lateral line. A falling barometer reduces the pressure on the swim bladder, letting fish move through the water column with less effort, and it precedes weather that will make feeding harder — so many species feed hard in advance. Rising pressure has the reverse effect, and fish need time to re-equalise, which is why the bite dies for a day or two after a front. A change of around 3–5 hPa over six hours is enough to be noticeable at the rod tip. Anything over 8 hPa in six hours is a strong signal — usually a front arriving, which means excellent fishing followed by a shutdown. Below about 2 hPa of movement, treat it as steady. It depends entirely on the species. Cold-water fish such as trout, grayling and salmon feed best between 6°C and 16°C (43–61°F). Cool-water species such as pike, perch and walleye peak around 10–20°C (50–68°F). Warm-water species such as bass and carp are most active at 18–26°C (64–79°F). The Fishing Bite Score adjusts the active band automatically for the fishery type you select, and the species matrix lists the band for twelve common species. Feeding switches on across almost every species. Fish shallow, fish confidently, fish now.
Scores are capped by dealbreakers — heavy rain, dangerous wind, thick fog or hazardous UV pull a day down no matter how pleasant the rest of the numbers look.
