Prayer times today in Surabaya, Indonesia: Fajr 04:18 AM, Dhuhr 11:33 AM, Asr 02:54 PM, Maghrib 05:24 PM, Isha 06:39 PM.
Islamic prayer times in Surabaya are calculated using the Kementerian Agama RI (Kemenag) method based on the geographic coordinates -7.2575° N and 112.7521° E, and are adjusted to the local Asia/Jakarta timezone. This system relies on precise solar depression angles to establish Fajr, Dhuhr, Asr, Maghrib, and Isha Namaz timetables.
Understanding Namaz and Prayer Time Calculations in Surabaya
For Muslims residing in or visiting Surabaya, establishing the five daily prayers (Salah or Namaz) stands as a foundational pillar of their faith. These prayers—Fajr (dawn), Dhuhr (noon), Asr (afternoon), Maghrib (sunset), and Isha (night)—must be performed within their specified astronomical windows. Finding precise timings is crucial to ensuring that acts of worship are aligned with the solar positions designated by Islamic law.
The local Muslim community in Surabaya has grown steadily, developing active centers of spiritual and civic engagement. Local religious life revolves around institutions like the Al-Akbar National Mosque (Masjid Nasional Al-Akbar). Surabaya features a deeply religious Muslim community, with Masjid Al-Akbar serving as the central hub. The community is highly active in Islamic boarding schools (Pesantren) and local charitable endeavors.
Historically, calculating these times required physical observation of the sun, shadows, and horizon colors. Today, modern science and astronomical algorithms allow us to calculate these windows with absolute mathematical precision. However, because these times are directly determined by the Earth's orbit and tilt relative to the sun, they shift slightly every day, requiring local Muslims to utilize dedicated tools to remain punctual.
The regional prayer calculations rely on exact angular thresholds. Fajr begins when the sun falls below the horizon at a specific angle, while Isha begins when the sun descends past another specified threshold.
Geographic coordinates play a vital role. With a latitude of -7.2575° N and a longitude of 112.7521° E, Surabaya experiences varying day lengths throughout the seasonal cycle. In the summer months, the sun rises earlier and sets later, which narrows the timeframe between Isha and the subsequent Fajr prayer. Conversely, in winter, the daylight hours shorten, causing Dhuhr, Asr, and Maghrib to occur closer together.
In addition to prayer times, determining the correct alignment towards the Kaaba in Makkah (the Qibla) is essential. From Surabaya, the Qibla bearing is calculated at 294° clockwise from true North. By utilizing our integrated math-based compass widget, users can easily locate this direction. Our tools automatically parse the latest astronomical data client-side, adjusting for local timezone offsets and Daylight Saving Time changes dynamically, guaranteeing accuracy without daily site rebuilds.
