Sun and Moon Times

The sun will be at it's highest point at . Today we have 15:2 hours of daylight. For shallow water fishing the twilight periods are often the most productive fishing times, especially on days when a major or minor time will coincide with twilight. In low light conditions predators have better cover for their ambush and often hunt in shallow water.

Next New Moon in ~15 days on 14th July
Full Moon is generally a productive time for fishing - especially night fishing. Bright nights mean that many predators feed more actively during the night. During full moon the gravitational pull is in line with the gravitational pull of the sun, affecting all wildlife and increasing feeding behaviour.
  • Distance to earth:
    405,485 km
    Proximity:
    0.5 %
We can compare the current moon distance to it's minimum and maximum distance from earth and express that as proximity. A high proximity means the moon is closer to earth. At 50% it would be at it's mean distance. A high proximity causes big tides, currents and has a direct effect on increased bite times. A proximity greater than 90% indicates a super moon.

7 Day Fishing Weather

The weather plays an important role in fishing. Wind strenght and direction often determine where you can fish and where fish might be holding. Although high pressure is usually good for fishing, steep pressure changes often trigger feeding frenzies and are great times for fishing. Of course temperature has also a strong effect on fishing and comfort on the water. So make sure to cross check the weather forecast with the solunar fishing times to determine the best times to go fishing.

Fishing Overview Boulder

Fishing in Boulder, Colorado revolves around pocket-water trout streams, canyon creeks, and a ring of Front Range reservoirs that give anglers year-round options. The backbone is Boulder Creek, which runs right through town and up into Boulder Canyon, but serious anglers also work nearby lakes and the high-country stillwaters west of town.

Seasonal patterns on Boulder Creek are driven by snowmelt and water clarity. Late March through May, pre-runoff, brings strong midge and blue-winged olive hatches; fish small nymph rigs (sizes 18–22) in slower seams. Runoff usually peaks in late May–June—look for clearer edges, side channels, and tributary inlets, and consider larger, flashy nymphs or streamers tight to the bank. July through early October is prime: dry-dropper rigs, terrestrial patterns, and attractor dries take aggressive browns and rainbows from riffles and pocket water. Late fall and winter demand subtle presentations: tiny midges, slow drifts in deeper wintering holes, and light tippet (6X) become critical.

Habitat types around Boulder range from small, technical creeks to open-water reservoirs. In-town Boulder Creek features manicured banks, boulder gardens, and short runs; the canyon stretch offers classic freestone pocket water with plunge pools and slot seams. Above Nederland and toward the Peak-to-Peak corridor, small alpine streams and lakes hold brook trout and cutthroat that reward stealthy approaches. East of town, prairie reservoirs and ponds provide weedlines, rock piles, and drop-offs that concentrate warmwater species like bass, walleye, and panfish.

Effective techniques depend on which water you’re targeting. On Boulder Creek, a dry-dropper setup is the everyday workhorse: a buoyant attractor or hopper pattern with a size 16–20 beadhead nymph 18–24 inches below. Focus on the soft inside edges of riffles, current breaks behind boulders, and the heads of pools where oxygen and food converge. Small streamers stripped or swung along undercut banks can move larger browns, especially on cloudy days or as light fades.

For reservoir fishing near Boulder, shore anglers do well targeting early and late low-light windows. Bass often stage around riprap, submerged timber, and weed edges—work these with suspending jerkbaits, 3–4 inch soft-plastic swimbaits, or finesse jigs. Walleye key on points and subtle breaklines; slow-rolling jig-and-plastic combinations along bottom contours is productive, particularly in spring and fall. Carp in local ponds respond to subtly presented jigs, nymph-style flies, or dough baits pitched ahead of cruising fish in the shallows.

Tactical tips: in the creek, think stealth and precise wading—keep a low profile, approach from downstream, and hit the first 2–3 drifts perfectly to maximize your chances. Adjust tippet strength and indicator depth frequently; small changes often double your hookups. In stillwaters, pay close attention to wind direction: wind-blown shorelines often push baitfish and insects, concentrating predators. Polarized sunglasses are critical both for spotting trout in clear runs and sight-fishing for carp and bass along rocky margins.

With small urban stretches, rugged canyon water, high lakes, and nearby reservoirs, the Boulder area gives anglers an unusually dense mix of fisheries within short driving distance, making it a strong base for both quick after-work sessions and full-day missions along the Front Range.
