Warm with some showers
Itajaí in December offers pleasant temperatures, with highs around 81°F and comfortable lows near 71°F. Rain is uncommon, with only about 4 rainy days expected across the month, ideal for beach days and shore excursions. Warm with some showers.
This is one of the most popular months to visit Itajaí, so book shore excursions early. The top snorkeling spots and tours sell out fast. Lightweight layers work well: a light cardigan for evenings on deck and breathable tops for port days cover most conditions.
