December to February: peak summer
December to February is high season in Bombinhas, with temperatures often reaching 30°C and above. The town's population swells with Brazilian holidaymakers, especially during the week between Christmas and New Year. Beaches like Praia de Bombinhas and Praia da Sepultura become very busy, and parking near the main access points fills early. Accommodation rates are at their highest, so booking well in advance is essential. If you thrive on lively atmosphere and warm sea temperatures—often around 24°C—this is your window, but expect queues at restaurants and limited space on the sand.
For those who don't mind occasional afternoon showers, January and February still offer plenty of sunshine. The water is warm and clear, ideal for snorkelling at Sepultura or taking a boat trip to the marine reserve. However, the crowds can be overwhelming for some. I'd recommend booking a hotel with a pool and secure parking if you visit now, as returning after a day at the beach can be stressful with limited parking. Also, note that many businesses operate at full capacity, so service might be slower than usual.
March to May: autumn calm
March marks the transition to autumn, with temperatures gradually decreasing to the mid-20s by May. The summer crowds thin out, especially after Carnival, making it an excellent time for a more relaxed experience. The sea remains warm enough for swimming until late April, and the water clarity is often superb for diving—visibility can exceed 15 metres at sites like Ilha do Arvoredo. Accommodation prices drop significantly, and you'll find it easier to secure a room with a sea view. This is my preferred period for a balance of comfort and quiet.
May brings cooler evenings, so pack a light jacket. Rainfall is moderate, but you can still enjoy sunny days. The annual Sardine Festival (Festa da Sardinha) typically takes place in May, celebrating the local catch with food stalls and music—a great way to experience local culture. Hotel rates are among the lowest of the year, making it a budget-friendly option. I'd book a hotel in the Centro area for easy access to restaurants and the beach, as some businesses may have reduced hours.
June to August: winter retreat
Winter in Bombinhas is mild, with daytime temperatures averaging 20°C. Rain is infrequent, and the sun often shines, though the sea breeze can make it feel cooler. This is low season, so you'll have many beaches almost to yourself—Praia do Ribeiro and Praia da Conceição are particularly peaceful. However, some restaurants and shops close for the season, especially in smaller neighbourhoods. Surfers will appreciate the larger swells, while divers might find the water cooler but still manageable with a wetsuit. Hotel prices are at their lowest, making it an attractive option for budget travellers.
If you're planning a winter getaway, consider staying in a hotel with heating, as evenings can be chilly. The lack of crowds means you can explore at your own pace, but check opening hours of attractions like the Bombinhas Marine Reserve Centre. I'd recommend this season for couples and retirees seeking tranquillity, but families with young children might prefer warmer months. Also, whale-watching season runs from July to November along the Santa Catarina coast, though sightings near Bombinhas are occasional.
September to November: spring awakening
September to November sees temperatures rise again, reaching the high 20s by November. The spring shoulder season offers a pleasant mix of sunny days and occasional showers. The beaches are relatively quiet, except during the October school holidays when Brazilian families flock to the coast. Accommodation prices are moderate, and you can often find good deals. The water is still cool for swimming in September but warms up by November. This is a great time for hiking and exploring the surrounding Atlantic Forest trails, such as the Trilha do Morro do Macaco.
November marks the beginning of the high season buzz, with businesses reopening and events like the Bombinhas Jazz Festival (usually in November) drawing visitors. I'd book a hotel early for November weekends, as they fill quickly. The spring is also ideal for stand-up paddleboarding and kayaking, with calmer winds. Overall, this period provides a good balance of decent weather and fewer crowds. For those looking to book, aim for late October or early November to avoid the school holiday rush and still enjoy comfortable conditions.
