Berwick, Atchafalaya River, LA Daily Water Report — August 27, 2026

Boating is the standout play today on the Atchafalaya River at Berwick, with a near-perfect 9.3 out of 10, and kayaking is right there with it at 8.9. Diving and fishing also score well, hitting 7.6 and 7.2 respectively. The key is a remarkably calm morning: winds are holding around 3 knots from the southeast, gusting only to 5, and wave heights are flat at 0.1 meters with a short 3-second period. That means the river surface is essentially glass through the early hours, ideal for getting a boat out or launching a paddleboard without fighting any chop. The catch is that a rain window opens from 7 a.m. to 11 a.m., though the representative precipitation is zero—so it’s more of a threat than a guarantee, but you’ll want to keep an eye on the sky. The air temperature is already 27.4°C with a feels-like of 33.5°C and humidity at 89%, so it’ll be sticky fast once the sun burns through the 2% cloud cover. Temps top out near 29°C by afternoon, but the wind nudges up past 8 knots around 7 a.m., so the real sweet spot is before that. Compared to yesterday’s similar 9.5 boating score and 9.2 kayaking mark, conditions are nearly identical, with the same light wind and calm water—you’re not losing much. Diving stays consistent with recent days at 7.5 or 7.6, and the water temperature is 32.3°C, which is a full 0.7°C above average for late August, so it’s bathwater warm. Visibility isn’t reported, but the chlorophyll data is not a substitute, so treat the diving score as a solid green light for comfort, not clarity. Fishing benefits from a solunar major period from 11:24 a.m. to 1:24 p.m., right when the pressure is stable at 1015 hPa and the wind remains low, giving you a decent midday window even as the breeze picks up. Wildlife watching scores 8 out of 10, driven by that same solunar timing and light wind, so early morning offers good odds of seeing birds and activity along the banks. Surfing is a predictable 4.5, with virtually no wave energy to work with—leave the board at home. Looking ahead, tomorrow and Friday keep the same flat, calm marine pattern with waves near zero and winds under 10 knots, so boating and kayaking will stay excellent. The weekend introduces a rising chance of rain, hitting 52% by Sunday and climbing above 55% into next week, so enjoy the stable window while it lasts. Best bet: get on the water before 7 a.m. and you’ll have the river to yourself with mirror-flat conditions and a soft southeast breeze.
