SWELLRADAR is requesting a verified marine run for Itamambuca.
Spot intelligence.
Itamambuca is calibrated as a sheltered river-mouth break rather than an open São Paulo beach. South-to-southeast groundswell and northwest wind are favoured, while the tide score stays adaptive to changing river banks.

Character
01Itamambuca is defined by right-favouring river-mouth banks with left and right beach peaks over sand banks shaped by the river mouth. The shape can change with swell angle, period and the active section, so the live score should always be paired with a visual check from shore.
Best setup
02S–SE groundswell swell, nw–nnw offshore and all tides · riverbank dependent form the profile baseline. SWELLRADAR treats 0.6–2.8 m as a working range, not a guarantee of breaking-wave size.

03Choose a peak that matches your experience and reassess it as tide and crowd change. Pay particular attention to river current and rip channels, runoff after rain, crowded peak. Local signs and advice always take priority.
