Prayer times for Houston

WhiskAI computes prayer times for Houston from the city's geographic centre (latitude 29.7604°N, longitude -95.3698°W) using the Islamic Society of North America (Fajr 15°, Isha 15°) calculation method. This is the convention adopted by the Islamic Society of North America and the majority of mosques across United States, which means our published times align closely with what most Houston mosques announce as the start of each prayer window.

Each calculation depends on the precise position of the sun relative to Houston's horizon at every moment of the day. Fajr is computed as the moment the sun reaches 15 degrees below the eastern horizon during dawn twilight. Sunrise is the moment the upper edge of the sun first appears above the horizon. Dhuhr is calculated when the sun crosses the local meridian — true solar noon for Houston's longitude — with a one-minute settling adjustment. Asr applies the standard Shafi'i shadow rule: the prayer begins when an object's shadow equals its own height plus the residual noon shadow. Maghrib begins at sunset, and Isha at 15 degrees below the western horizon during dusk twilight. We retrieve fresh values from the Aladhan API daily and cache them for 24 hours per city.

Houston sits at a sub-tropical latitude (29.76°N), which produces a meaningful seasonal swing in daylight hours. On the summer solstice in late June, Houston experiences approximately 13 hours 55 minutes of daylight from sunrise to sunset. On the winter solstice in late December, daylight contracts to roughly 10 hours 5 minutes. The annual variation between longest and shortest day is therefore close to 3 hours 50 minutes — a substantial range that directly shapes the daily fasting window during Ramadan.

When Ramadan falls in summer (it last did in 2014–2017 and will again in 2042–2045 under the lunar calendar's 33-year drift), Houston Muslims fast for close to 12 hours 55 minutes from Fajr to Maghrib. When Ramadan falls in winter (as in 2027–2030), the fast contracts to roughly 9 hours 35 minutes. The current Ramadan window — Ramadan 1448 begins around 15 February 2027 — places fasting in late winter for Houston, producing moderate to short fasting days. Late summer twilight that produces an Isha after 22:00 in northern cities is a defining feature of summer Ramadan in United States.

WhiskAI publishes calculated adhan times — the moment each prayer's astronomical window opens. Mosques in Houston typically publish iqamah times that delay the start of congregational prayer beyond the adhan to give worshippers time to gather and prepare. Most American mosques delay iqamah by 20 to 30 minutes after Fajr adhan and 10 to 20 minutes after the four daytime prayers. Maghrib iqamah is usually shorter, often only 5 to 10 minutes after adhan, because the Maghrib window itself is brief — the prayer must be completed before the start of Isha.

Iqamah practice varies between mosques even within Houston, reflecting community tradition and congregational preference. Islamic Society of Greater Houston (ISGH) Main Center publishes its own iqamah schedule on its noticeboard and website, and the difference between two Houston mosques can be ten or fifteen minutes for the same prayer. For congregational prayer, always defer to your local mosque's published iqamah times rather than the calculated adhan times shown here. For private prayer at home or while travelling, the calculated adhan times on this page are accurate to within a minute.

Friday prayer is held in congregation across American mosques, typically between 12:30 and 13:30 with multiple sittings in city-centre locations to accommodate office workers. In Houston, the Jumu'ah service replaces the Friday Dhuhr for those who attend in congregation, consisting of a two-part khutbah followed by two cycles of congregational prayer. The full service typically runs 30 to 45 minutes from the start of the first khutbah to the conclusion of prayer.

With 2 notable mosques listed for Houston, worshippers have a choice of congregations. Larger American mosques in city-centre locations often hold multiple Jumu'ah sittings to accommodate office workers, with the first sitting starting close to Dhuhr and a second sitting 45 minutes later. Khutbah language varies by mosque; in Houston the bulk of the sermon is typically delivered in English with formal opening, Quranic recitation, and supplication in Arabic. Some Houston mosques deliver portions of the khutbah in community languages such as Urdu, Bengali, Arabic, Somali, or Turkish.

WhiskAI lists 2 notable mosques for Houston, drawn from public sources and verified against each mosque's own publication. Islamic Society of Greater Houston (ISGH) Main Center; Masjid Bilal. These institutions serve the city's primary congregational worship, host taraweeh prayers during Ramadan, and coordinate community resources including funeral services, marriage registrations, and Islamic education.

Mosque listings on WhiskAI are not exhaustive — Houston hosts many smaller community prayer rooms, family-led gatherings, and pop-up congregations not listed here. The mosques shown represent the most publicly recognised institutions with verifiable street addresses. To suggest an addition or report a correction, contact us through the editorial team. Mosque addresses are reviewed quarterly against public directories including the ISNA and the ICNA centre listings.

Houston sustains a diverse halal food landscape spanning Arab, South Asian, African, and Latin American culinary traditions, with restaurants, butchers, and grocery stores serving halal-compliant meat under the supervision of recognised certification bodies. With a metropolitan population of approximately 2,304,580, Houston's halal sector concentrates around mosques and historically Muslim residential neighbourhoods, with newer halal-friendly chains expanding into city-centre and suburban shopping districts.

Beyond food, Houston's Muslim community is supported by Islamic schools, weekend madrasas, charitable organisations operating zakat and food bank programmes, and sister-city links to communities across the wider Muslim world. WhiskAI does not maintain a comprehensive directory of these resources; readers seeking specific community services should contact the institutions listed in the mosques section above, which typically maintain or signpost relevant local resources.

Travellers visiting Houston can use WhiskAI to plan prayer times during their trip. The five daily prayers must be observed wherever you are, and the calculated times shown on this page apply to the city centre and immediate surroundings — geographic variation within the metropolitan area produces differences of less than a minute, well within standard observance precision. The city's time zone is America/Chicago, which WhiskAI handles automatically through the Aladhan API.

Islamic jurisprudence permits travellers to combine and shorten certain prayers (qasr and jam'). Specifically, Dhuhr and Asr may be combined and shortened to two cycles each, and Maghrib (which remains three cycles) may be combined with Isha (shortened to two). The threshold distance and travel circumstances that trigger these dispensations vary across schools of thought. Houston mosques are accustomed to serving travelling Muslims and welcome visitors at all five congregational prayers and at Jumu'ah on Fridays.

As of the most recent calculation, the next prayer in Houston is Fajr, scheduled to begin at 05:35 local time — approximately 209 minutes from now (3 hours 29 minutes). The five daily prayers in Houston today fall at Fajr 05:35, Dhuhr 13:19, Asr 16:55, Maghrib 19:55, and Isha 21:05. Sunrise is at 06:44.

These values refresh daily from the Aladhan API and are governed by Houston's latitude, longitude, and the chosen ISNA calculation method. Coordinated through ISNA, ICNA, and the Fiqh Council of North America with individual mosques operating independently.
