Makassar and the surrounding areas host a surprising number of events and festivals; there's something on almost every week, including markets, music concerts, a half-marathon, a traditional fishing boat race, a chocolate festival, traditional games ... the list goes on. The problem can be finding out about them in advance. Here are some of the recurring ones, and some links to sources of event information.

Pantai Losari Market: Every Sunday morning from around 6 a.m. there is a general market (clothing, souvenirs, food) along the waterfront, centred around the Stella Maris Hospital area.
Aerobics: From about 7 a.m. every Sunday you can take part in one of the biggest public aerobics sessions you'll likely to witness, at Pantai Losari. To see the local ladies in their brightly coloured jilbabs and lycra is a cultural moment. The pace is pretty frenetic, so keep up if you can. There is also a session at Lapangan Karebosi (Karebosi Sportsground) at the same time.
Makassar Hash Run: The local branch of the Hash House Harriers, a group of "non-competitive lazy runners, professional drinkers, and noisemakers", organises a run/walk every Saturday at 4.00 pm. Facebook page: https://www.facebook.com/groups/218806022043/
June Makassar International Writer's Festival: Yes, Makassar has its own writers' festival, organised by Rumata' Artspace since 2011. The festival has a relaxed and informal atmosphere with an eclectic program of stimulating and entertaining conversations featuring writers from Indonesia and overseas. Multi-language.

August Makassar Street Festival: Bands, street soccer, food – a community festival for Makassar.
Independence Day Celebrations: On or around 17 August there are celebrations to commemorate Independence Day. Ask around and look out for signs. The usual venues are Pantai Losari (the waterfront), Karebosi sports ground and Benteng Fort Rotterdam.
Toraja International Festival: Not in Makassar, obviously, but a good reason to head up to Tana Toraja. A 3-day festival of world music and dance held at the dramatic venue of Ke'te' Kesu just out of Rantepao. Website: http://torajainternationalfestival.com/
September Coklatku, Budayaku, Indonesiaku (My Chocolate, My Culture, My Indonesia): Sulawesi is one of the world's major cocoa growing regions. This annual festival celebrates chocolate. What's not to like? Website: http://www.bbkp-makassar.com/
Musik Hutan (Jungle Music Festival): Music/dance event that is held out of town, usually in Maros. The event supports retaining Sulawesi's quickly disappearing natural forest and animal species. Website: http://musikhutan.com/
Makassar's birthday (aka Festival Losari): Various events to celebrate the birthday of the city. (It was 407 in 2014.)
Here are some other places you can get a heads-up about forthcoming events. Unfortunately the official Department of Tourism website is particularly lacking in information and out of date. But maybe that will change ... http://www.tourism-makassar.com/index.php
