3) Low Season in Bali
The low season in Bali, in terms of hotel bookings, are roughly the first and last quarters. In other words, right after the New Year (from January to March), and the last quarter (October to November. December usually has a fair amount of 'holiday season' bookings). The wet Bali weather around these months also see residents having their umbrellas and ponchos at hand.
You can expect lower hotel rates around this time, together with all sorts of benefits on offer. You can also anticipate lesser crowds during these months. Quieter roads allow for faster access times from your hotel to locations of interest. This is true during certain national holidays. One such time of the year is the Muslim holy month of Ramadan. It's main celebration is on the day of Eid-ul-Fitr, or 'Idul Fitri'.
The reason for this ‘quieter’ scene is due to much of the non-Balinese populace departing from the island. They usually head home for the holidays. A similar circumstance is in the densely populated southern region and business districts of Bali. Particularly, over the Nyepi, 'silent day' or Saka New Year celebrations. Residents return to their respective homes in rural areas to rejoice with their families.
Expect the peak season in Bali around Christmas and New Year, from December 24 to January 5. A dry season equivalent, which also coincides with school holidays, is between July 1 and September 30.
