CatchWindow fishing intelligence

Callao, Peru Daily Water Report — September 1, 2026

Today's water conditions in Callao harbor offer a mixed bag of opportunities for water enthusiasts. Surfers and divers will find the most favorable conditions, while kayakers might want to consider other plans. With a surfing suitability score of 7.6 out of 10, the consistent 1.58-meter waves and a steady swell from the south make for a decent day on the board. Divers score even higher at 7.8, thanks to the calm winds and warm sea surface temperature of 22°C, though visibility might not be at its peak. Fishing scores a respectable 6.4, holding steady with recent days. While solunar periods suggest some activity, the lack of tidal data means anglers will need to rely on intuition and local knowledge. Boaters and sailors face moderate conditions with scores of 6.4 and 6.8, respectively. Winds are relatively light, gusting up to 21 knots at noon, which could make for a brisk sail but might challenge smaller crafts. Kayakers, however, will find the conditions less forgiving, scoring only 4.7. The combination of wind and wave conditions makes for a choppy paddle, so it might be best to plan for a calmer day. Wildlife observers have a decent 6.8 score, suggesting some activity, but nothing out of the ordinary. Compared to recent history, today's conditions are slightly warmer and less windy, with the sea surface temperature anomaly at a notable +5.9°C. Looking ahead, similar conditions are forecasted with moderate winds and stable temperatures, though the wave heights are predicted to slightly decrease. For those looking to catch the best of the day, aim for the late evening when the waves are at their calmest around 22:00, providing a smoother experience whether you're on a board, boat, or just enjoying the sunset.
