CatchWindow fishing intelligence

Monterey, CA Daily Water Report — August 27, 2026

Today is a winner for wildlife watchers and divers, with the best chance in days for spotting surface activity and getting a clear look below. Fishing and surfing are solid second acts, but leave the small sailboat tied up — the breeze isn’t cooperating. The marine layer is thick this morning, with overcast skies and humidity near 90 percent, but the surface itself is unusually calm. Wind is barely a zephyr out of the west at 3 knots, gusting only to 8, and the calmest stretch of the day should arrive around 11:00 when wave heights bottom out at 1.3 meters. That may sound big, but the swell is short-period — 1.1 meters at 5.3 seconds — so it’s a lumpy, disorganized sea rather than a smooth roller. For boaters and paddlers, that’s a manageable chop with a 6.4 and 5.9 score respectively, a slight step down from yesterday’s better windows. Surfers will find peaky, workable waves in the 7.5 range, similar to recent days. What really stands out is the wildlife score at 8.4, the highest in the past week. The solunar minor period from 06:01 to 07:01 has already passed, but the major window near midday, 11:31 to 13:31, aligns with the calmest water. The greenish tint in the water column from elevated chlorophyll doesn’t guarantee fish or bait, but the pattern of score improvement compared to yesterday’s 7.3 suggests something has shifted. Divers also get a top-tier 7.8, helped by light wind and relatively warm sea surface temperatures at 14.7°C, which is a full 2 degrees above average for late August. Things get a bit more active starting Friday. Winds will pick up toward 8-10 knots through the weekend, and waves build slightly to 1.5-1.7 meters, making small-craft conditions less appealing. The real prize appears early next week: by September 1, swell drops to 0.5-1.0 meters and waves ease into the sub-meter range, offering a rare flat-water window for kayakers and boaters. Your best bet today is to be on the water between 11:00 and 1:00 with a pair of binoculars, a mask, or a fishing rod — the calmest hour of an otherwise middling day.
