Callao, Peru Daily Water Report — August 25, 2026

Today's conditions in Callao harbor cater to a range of water activities, with surfing taking the crown at a solid 9/10. The waves are rolling in at 1.3 meters with a decent period of 9.15 seconds, and a swell coming from the southwest. Surfers will find the morning hours particularly inviting, with the calmest waves around midnight, though the wind may pick up later in the day with gusts reaching up to 24.7 knots by 8 PM. For those looking to dive, a score of 8.1/10 suggests good conditions thanks to manageable wind and waves, and a warmer-than-usual sea surface temperature of 21.7°C. Visibility, however, is quite limited at just 0.44 km, so divers should proceed with caution and ensure they're well-prepared for lower underwater clarity. Boaters and kayakers should be aware of the easterly winds, which are fairly steady at 5 to 9 knots but can gust significantly in the evening. Boating scores a 6.6/10 and kayaking a 6/10, indicating decent conditions but with a need for vigilance, especially in the afternoon when the wind is at its peak. Fishing stands at 5.9/10, unchanged from previous days, with solunar periods potentially providing the best catch opportunities around 1:51-3:51 AM and 1:51-3:51 PM. The high chlorophyll levels might suggest good baitfish activity, but remember, it's not a guaranteed catch. Looking ahead, the weather remains stable with no rain expected and temperatures holding steady. Winds will continue to be a factor but should slightly ease over the next couple of days, making for potentially better boating and kayaking conditions. As for surfing, the wave patterns suggest consistency, but expect some variability in height and swell direction later in the week. Best bet: Hit the surf early to ride those clean morning waves before the wind kicks up!
