Introduction

September in Bali marks the end of the dry season, a time when the island begins transitioning towards its wetter months. However, you’ll still enjoy plenty of sunshine, warm temperatures, and the gentle, refreshing breezes typical of Bali’s late dry season. Fewer tourists compared to August mean you can explore with more space to yourself, and outdoor conditions are still near-perfect for a range of activities.

Temperature Overview in September

September’s temperatures in Bali remain warm and pleasant, typically ranging between 26°C to 30°C (79°F to 86°F) during the day. Nights cool slightly, with temperatures averaging around 22°C to 24°C (72°F to 75°F), making it comfortable for evening outings and al fresco dining experiences.

Daytime vs. Nighttime Temperatures

Daytimes in September are ideal for enjoying the beach, exploring cultural landmarks, or hiking. Nights are mild enough to stroll around without any heavy layers, though a light shawl or jacket can be useful in the cooler highland areas, such as Ubud.

Humidity and Rainfall

Humidity levels in September are a bit higher than August, averaging around 75%, but still lower than the rainy season months. Rainfall is minimal, with occasional brief showers that rarely interrupt outdoor plans. September averages 3 to 5 rainy days, often isolated to short bursts in the early morning or evening.

Rainfall Patterns

Rainfall in September tends to be brief and scattered, mostly in the early mornings or late evenings. These short showers bring a refreshing coolness to the air and tend to add a vibrant touch to the lush greenery, enhancing Bali’s scenic beauty without dampening your itinerary.

Sunshine and Daylight Hours

September provides an average of 8 to 9 hours of sunshine per day, giving travelers ample daylight for excursions, sightseeing, and beach time. With longer days, it’s easier to pack in more activities or simply relax and unwind under Bali’s tropical sun.

Best Times for Outdoor Activities

The early morning and late afternoon are perfect for exploring Bali’s temples, markets, and rice terraces. Midday sunshine is ideal for beachgoers and water sports enthusiasts, while the evenings are comfortably cool for outdoor dining or watching traditional Balinese performances.

Ocean Conditions and Activities

September’s ocean conditions are favorable for most water-based activities. The water temperature remains around 27°C (80°F), perfect for long swims, snorkeling, and diving. Although waves are slightly calmer than in peak surf season, surf spots still see consistent waves for surfers at all levels.

Snorkeling and Diving

With great visibility and warm water, September is a fantastic month for snorkeling and diving. Dive sites like Tulamben, Nusa Penida, and Amed offer clear underwater views of Bali’s coral reefs and marine life, including tropical fish, manta rays, and sometimes even sea turtles. Divers can enjoy peaceful conditions and capture vibrant underwater photos.

Surfing Conditions

Although September marks the end of peak surfing season, there are still consistent waves along Bali’s southern and western beaches. Uluwatu, Canggu, and Kuta remain popular, with waves that suit both beginners and experienced surfers. Early mornings offer the best conditions for catching smooth, steady waves.

Travel Tips for Bali in September

Here are some helpful tips to make the most out of your Bali adventure in September:

Pack for the Weather

With warm days and comfortable evenings, pack light, breathable clothing, swimwear, sunscreen, and comfortable footwear. A light scarf or jacket can be handy for visiting cooler areas like Ubud, especially at night.

Stay Hydrated

The tropical sun and increased humidity make it essential to stay hydrated. Bring a refillable water bottle as Bali has many places where you can refill it. This helps both your health and the environment by reducing plastic waste.

Enjoy Bali’s Cultural Events

September often includes cultural festivals and events, allowing travelers to experience Bali’s rich traditions up close. Check local event calendars to see if there are any traditional ceremonies, dances, or art festivals taking place during your visit.

Plan for Morning or Late Afternoon Adventures

Given the warm midday sun, schedule excursions, hiking, and temple visits during early morning or late afternoon hours for cooler, more comfortable temperatures. These times also offer the chance for quieter experiences and picturesque lighting for photography.

Before you take off make sure to check with local government of the travel status.
