About Surabaya Time Zone
Surabaya uses the Asia/Jakarta IANA time zone, which operates at UTC+7 year-round. This time standard is known in Indonesia as WIB (Waktu Indonesia Barat) or Western Indonesia Time, and it applies not only to Jakarta but also to major parts of western and central Indonesia, including Java, where Surabaya is located.
Surabaya does not observe daylight saving time, so its offset remains UTC+7 throughout the entire year. That stability is helpful for international scheduling because the local time in Surabaya does not shift seasonally, although the time difference with countries such as the United States, United Kingdom, and Australia can still change when those countries enter or leave DST.
Geographically, Surabaya is in East Java, on the northeastern coast of Java Island, but it still follows the same Asia/Jakarta time zone as Jakarta in western Java. Indonesia spans three main time zones: WIB (UTC+7), WITA (UTC+8) for places such as Bali and Makassar, and WIT (UTC+9) for eastern regions like Jayapura, so Surabaya is 1 hour behind Bali and 2 hours behind Papua.
Surabaya City Details
Surabaya is the capital of East Java and one of Indonesia’s most important commercial and port cities, with a population of 2,874,314. It is a major center for shipping, manufacturing, trade, education, and regional administration, making accurate time coordination important for business calls, cargo planning, and intercity travel.
The city is located at -7.24917°, 112.75083°, placing it on the northern side of East Java near the Madura Strait. Its coastal position supports major maritime activity through the Port of Tanjung Perak, one of Indonesia’s busiest ports, which is relevant for freight forwarders, import-export firms, and vessel scheduling across Southeast Asia.
Surabaya uses the Indonesian rupiah (IDR) as its official currency, and the country dialing code is +62. If you are arranging calls, hotel bookings, or local business contacts, numbers in Surabaya will generally be reached through Indonesia’s international calling code, while payments, invoices, and local pricing will be quoted in rupiah.
Time Differences from Surabaya
Surabaya is 7 hours ahead of UTC, and because it does not use daylight saving time, its offset stays fixed at UTC+7 all year. The practical difference with other cities changes seasonally only when those cities move their clocks forward or back.
Compared with New York, Surabaya is usually 12 hours ahead during Eastern Standard Time (EST, UTC-5) and 11 hours ahead during Eastern Daylight Time (EDT, UTC-4). When it is 9:00 AM in Surabaya, it is 9:00 PM the previous day in New York during EST, or 10:00 PM the previous day during EDT, which means Surabaya mornings often align only with late evening in the US East Coast.
Compared with London, Surabaya is 7 hours ahead during Greenwich Mean Time (GMT, UTC+0) and 6 hours ahead during British Summer Time (BST, UTC+1). When it is 9:00 AM in Surabaya, it is 2:00 AM in London during GMT or 3:00 AM during BST, so late afternoon in Surabaya is usually more realistic for UK business calls.
Compared with Tokyo, Surabaya is consistently 2 hours behind, because Tokyo uses JST (UTC+9) and does not observe DST. When it is 9:00 AM in Surabaya, it is 11:00 AM in Tokyo, making Japan one of the easier major markets to coordinate with during the same business day.
Compared with Sydney, Surabaya is 3 hours behind during Australian Eastern Standard Time (AEST, UTC+10) and typically 4 hours behind during Australian Eastern Daylight Time (AEDT, UTC+11). When it is 9:00 AM in Surabaya, it is 12:00 PM in Sydney during AEST or 1:00 PM during AEDT, which is useful for regional operations, aviation, and education scheduling across Asia-Pacific.
Compared with Dubai, Surabaya is 3 hours ahead, since Dubai uses GST (UTC+4) and does not observe daylight saving time. When it is 9:00 AM in Surabaya, it is 6:00 AM in Dubai, so Surabaya afternoon hours often create a better overlap for UAE-Indonesia trade, procurement, and shipping communication.

What is the time difference between Surabaya and New York?

For calls from the US, the best window is usually evening in the US and morning in Surabaya, or early morning in the US and evening in Surabaya, depending on the coast. For example, a 7:00 PM call in New York during EST is 7:00 AM the next day in Surabaya, while West Coast teams often find late afternoon Pacific time more practical for reaching Surabaya the following morning.
What is the best time to call Surabaya from the UK?
