Florianópolis, Santa Catarina tides 2026

Tide times for Florianópolis, Santa Catarina, santa catarina (brazil) across 2026. This page covers all twelve calendar months: every high, every low, the spring-neap cycle, and the biggest swings of the year. Spring tides cluster around new and full moons, when the sun and moon line up to amplify the gravitational pull on coastal water — that's when the daily tidal range is biggest at Florianópolis, Santa Catarina, both in highs above MSL and in lows below it. Neap tides land on the quarter moons, when sun and moon work against each other — the daily range compresses, the highs come down, and the lows come up. Within 2026, you'll see this rhythm repeat roughly every two weeks. The biggest swings of the year typically land around the perigean spring tides, when the moon is closest to Earth at the same time it's new or full.
