Fishing Forecast

Fishing weather forecast · Bite analysis · Bite index

A 7-day bite index for anglers in China, built from the weather and the local geography, with the best fishing times, spot/depth/bait tips and safety alerts. Search rivers, lakes, reservoirs and bays, or tap the water on the map.

Searching a water body (river, lake, reservoir, bay) is more precise than a city; for long rivers you tap the stretch on the map.

Pick a fishing spot to see the next 7 days.

How the bite index works

How does fishing weather become a bite index?

  • Every hour gets a 0–100 score from eight weighted factors: water temp 25, pressure 20, temperature trend 15, wind 10, sky 10, time of day 10, moon/tide 5, water body 5.
  • Each hour's score is averaged with its neighbours; the day's bite index is 60% the average of its best 6 hours and 40% the average of the whole day, so it reflects both how good the best hours are and how the day holds up overall.
  • Days with thunderstorms, strong gusts or high waves are capped at 60; three or more hours of storms or high waves cap the day at 45, and the card shows why.
  • 80+ excellent: pick the right hours and expect steady bites; 65–79 good: you should get bites; 50–64 fair: fishable but slow; 35–49 poor: tough, stick to the best window; below 35 not advised: bad or unsafe weather.

Is the water temperature estimated?

  • Yes. Rivers, lakes and reservoirs use the last 5 days of air temperature (recent days count more); the coast uses the sea-surface temperature.
  • Water inside the species' comfort range scores full marks; the further outside, the lower.

How are the best fishing times picked?

  • Take the best hour of the day plus an hour either side as a window, then the next best, up to 3 windows; poor ones are left out.
  • Sunrise, sunset and the moon periods (moon overhead, underfoot, rising or setting) earn a bonus; in hot weather 22:00–02:00 is included for night fishing.

Sea fishing and tides; how do rivers and reservoirs differ?

  • Sea: choosing a bay or coast brings in tide, wave height and sea temperature; the first hours of the flood or ebb score higher, slack water lower, and waves above 1.5 m are marked down.
  • Rivers: more than 30 mm of rain in two days means high, muddy water, so look for back-eddies, slow current and the downstream side of bridge piers; for long rivers tap the stretch you are going to.
  • Reservoirs: deep water stays cooler in the hot season; look for back bays, points and old river channels.

Does it work for bait and lure fishing?

  • Yes. Crucian, common and grass carp get bait-flavour tips; culter, bass, snakehead, mandarin fish and sea bass get lure-type tips.
  • The species sets the comfortable water temperature: too cold or too hot and the fish are sluggish, so the whole day is marked down; crucian carp ice fishing is marked down less.

Where does the data come from?

  • Weather, waves and tides come from public weather data; the location and type of rivers, lakes and reservoirs come from open map data; the base map is AMap or OpenStreetMap.
  • Sun and moon times are worked out on your own phone or computer; this site has no server collecting data and does not record your location.
  • The water type is recognised automatically and can be wrong, so you can change it; if it cannot be recognised, generic water is assumed.
Estimated from the weather and experience, with no guarantee of fish; check local closed seasons before you go. The Yangtze basin is under a 10-year fishing ban, and local closed seasons and no-fishing zones follow local notices. Stay away from the water in thunderstorms and never cast under power lines.
