Best Fishing Times for Lake Beulah
14-day solunar fishing calendar for Lake Beulah, Walworth County, Wisconsin — sun and moon times calculated for lat 42.811, lon -88.416.
Lake Beulah earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Lake Beulah is unusually deep for Wisconsin at 58 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Lake Beulah covers 812 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Walworth County's 35 graded lakes, Lake Beulah ranks 23 — below the local median, though not at the bottom.

How to Read This Calendar
Major periods (≈2 hours) are centered on lunar transit (when the moon is highest in the sky) and lunar opposition (when the moon is directly underfoot). These are typically the strongest feeding windows.
Minor periods (≈1 hour) are centered on moonrise and moonset. They're secondary windows that often produce well — especially when they coincide with sunrise or sunset.
Day rating combines moon phase (peak near new and full moons, when lunar gravity is strongest) with the overlap of major periods and the dawn/dusk twilight. A 4–5 star day stacks all three.
At Lake Beulah (lat 42.81°N), the longest day of the year is around June 21 with 15h 20m of daylight. The shortest is around December 21 with 9h 1m. Plan summer trips around the early-morning bite (around 5:30 AM) and the long evening window before sunset.
Frequently Asked Questions
What is the best time to fish Lake Beulah today?
Today's solunar calendar for Lake Beulah (lat 42.81, lon -88.42) shows sunrise at 5:22 AM and sunset at 8:34 PM. The strongest fishing windows are around major solunar periods at 4:43 AM–6:43 AM and 5:05 PM–7:05 PM, plus the 30-90 minutes around dawn and dusk.
What does the moon phase mean for fishing Lake Beulah?
Solunar theory holds that fish activity peaks during major periods (when the moon is overhead or directly underfoot) and minor periods (moonrise and moonset). Fish feeding tends to intensify during the days surrounding the new moon and full moon, when lunar gravity is strongest. Today's moon at Lake Beulah is Last Quarter (58% illuminated).
When are the longest and shortest days at Lake Beulah?
At Lake Beulah's latitude (42.81°N), the longest day of the year is around June 21 with about 15h 20m of daylight. The shortest day is around December 21 with about 9h 1m of daylight. Sunrise and sunset shift by roughly 6 hours between solstices.
Are major or minor solunar periods more important?
Major periods (about 2 hours, centered on lunar transit and lunar opposition) are generally considered the strongest feeding windows. Minor periods (about 1 hour, centered on moonrise and moonset) are secondary but still productive — especially when they overlap with sunrise or sunset.
