The large Current Fishing Score above uses current conditions and, on eligible river pages, can include a conservative USGS streamflow penalty. The seven daily cards remain weather-only because this site does not predict future river flow. Cards marked “Partial” use less than 90% of the weighted weather inputs.

Clear Lake fishing conditions overview

The current weather inputs produce a good weather-based Fishing Score. Very light wind may leave clear, calm water more demanding.

Estimated activity windows: 5:44 AM–7:59 AM and 6:32 PM–8:47 PM local time. These are dawn/dusk windows, not guaranteed bite times.

Best fishing time today: estimated windows

The first estimated window runs from 5:44 AM–7:59 AM, around sunrise at 6:29 AM. The second runs from 6:32 PM–8:47 PM, around sunset at 8:02 PM. Lower light can change visibility and fish positioning, but actual feeding periods vary by species, season and water conditions.

Clear Lake fishing: structure, seasons and local conditions

Natural northern California lake with productive shallow cover and offshore structure. For fishing decisions, useful local reference areas include coves and protected pockets. Those features are more informative than treating the whole forecast area as one uniform piece of water. The shallow character of Clear Lake means wind and short warming or cooling periods can affect a larger share of the fishable water quickly. Protected pockets may behave differently from exposed flats on the same day.

Seasonal change at Clear Lake is best treated as a sequence of warming, peak-summer and cooling periods. Each transition can change depth use, current preference and the value of shoreline cover. The seven-day forecast helps identify short weather shifts inside that cycle, but water temperature, flow or level should be checked whenever a reliable local observation is available. On Clear Lake, compare the daily score with the exposure of coves and protected pockets; those areas can respond very differently to the same wind and sun.

Common targets at Clear Lake include Largemouth bass, Crappie, and Catfish. They do not use depth, current and cover in exactly the same way, so the Fishing Score remains a conditions index rather than a species-specific bite prediction. There is no guarantee of a verified water sensor at the forecast point, so local temperature, clarity, level or current observations still matter.

What to watch in today's conditions

Wind

Current wind is about 2 mph from SSW, with gusts near 3 mph. Wind can improve surface movement on exposed banks while leaving coves and lee shorelines much calmer.

Barometric pressure

Current NWS pressure is missing, so pressure is excluded from this update and the Fishing Score is visibly marked as partial.

Moon phase and light

The moon is currently in the Waxing Crescent phase with approximately 38% illumination. Lunar illumination has a smaller weight than the main weather factors.

Always verify current state fishing regulations, seasons, bag limits, licensing requirements and location-specific closures before fishing.

How this forecast is calculated

The Fishing Score starts with National Weather Service weather data: pressure 28%, wind 24%, cloud cover 18%, precipitation probability 18% and lunar illumination 12%. Missing weather factors are never treated as zero; partial weather results are pulled toward a neutral 5/10 according to the missing weight. On eligible river pages, a separate conservative USGS flow check can only reduce the current score when streamflow is unusually far from the long-term seasonal median or changing rapidly. It never increases the score.
