What time is it in Portsmouth right now?

The time in Portsmouth, United Kingdom is 5:21 pm, 17:21 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the Europe/London rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Portsmouth sits at 50.80 degrees north and 1.09 degrees west, well into the temperate belt and 5,649 km from the equator. Its clock is set to a zone whose nominal meridian is 15.0 degrees east, and the city itself is 16.1 degrees west of that line. Those 16.1 degrees are worth 64 minutes 22 seconds of sun time, which is most of why solar noon here lands at 12:55 pm rather than on the stroke of twelve.

Portsmouth time zone and UTC offset

The IANA zone for Portsmouth, United Kingdom is Europe/London. Right now it is running at UTC+1 and the abbreviation in force is BST. Portsmouth is on summer time at the moment, which is why the offset reads UTC+1 rather than the UTC+0 it keeps in winter.

Where Portsmouth is on the map

The marker sits at the coordinates this whole page is computed from, so the sun times, the distances and the solar noon above all belong to this exact point rather than to the wider metropolitan area.

Time difference between Portsmouth and major cities

Every row below is computed at this instant, so daylight saving on either side is already in it. A positive figure means that city's clock reads later than Portsmouth.

Best time to call Portsmouth

Treating a working day as 9am to 6pm on both sides, this is the window the two cities genuinely share. Some of these pairs have no shared working hour at all, which is worth knowing before a meeting is proposed.

Cities on Europe/London time

107 of our cities keep Europe/London, so every one of them reads 5:21 pm at this moment and changes its clocks on the same night as Portsmouth. Nearest first:

Moon phase over Portsmouth tonight

The moon is a waning gibbous tonight, 16.5 days into its cycle and about 96% lit. The next full moon falls on October 26, 2026 at 4:11 am London time, and the next new moon on October 10, 2026 at 4:49 pm. Both are the same instant everywhere on Earth, printed here on the Portsmouth clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Portsmouth

The next change is on Sunday, October 25, 2026, 27 days from now, when the clocks in Portsmouth go back 1 hour at 1:59 am and the offset moves from UTC+1 to UTC+0.

Two things follow from that. Any standing call with Portsmouth shifts by an hour on that date unless the other side moves the same weekend, and every offset printed on this page is the offset for today rather than a fixed property of the city.

How far Portsmouth is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Portsmouth is Southampton, United Kingdom at 25 km, and the furthest is Dunedin, New Zealand at 19,188 km, which is 96% of the way to being exactly opposite.

The antipode of Portsmouth

Dig straight through the centre of the Earth from Portsmouth, United Kingdom and you come out at 50.80 degrees south, 178.91 degrees east. That point is near Dunedin, New Zealand. The nearest city in our catalogue to it is Dunedin, New Zealand, 827 km away from the antipode itself, where the clock currently reads 5:21 am on Monday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 50.80 degrees north becomes 50.80 degrees south, and 1.09 degrees west becomes 178.91 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Portsmouth is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC-11, roughly twelve hours from Portsmouth, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Portsmouth

Today the sun rises in Portsmouth at 6:58 am and sets at 6:52 pm, giving 11 hours 53 minutes of daylight. The dedicated page for this city carries the month by month table, the longest and shortest days of 2026, the golden and blue hour bands at both ends of the day, and all three twilight stages: sunrise and sunset times in Portsmouth.

Sun and moon in Portsmouth today

The sun is up in Portsmouth for 11 hours 53 minutes today, from 6:58 am to 6:52 pm. The moon sets in Portsmouth at 7:55 am and comes up again at 6:46 pm. The next phase is the last quarter on October 3, 2026. The moon is full, or as near to it as makes no difference, and the whole of the face turned towards us is lit.

Twilight is graded by how far the sun has dropped below the horizon. Civil twilight ends six degrees down, which is roughly the point at which you need a light to read outside. Nautical twilight ends at twelve degrees, when the horizon at sea stops being usable for a sextant sight. Astronomical twilight ends at eighteen degrees, which is full darkness for an observer.

Golden hour is the stretch with the sun between six degrees above the horizon and four below it, and blue hour runs from there down to six degrees below. Neither is literally an hour: each is as long as the sun takes to cross those few degrees, which is minutes near the equator and can be most of the evening at high latitude.

Moonrise and moonset are computed to the moment the moon's upper edge touches a flat horizon, allowing for refraction, for the size of the disc and for the moon's parallax, which together put the centre of the moon at 0.125 degrees above the horizon at the instant it rises. That is a different horizon from the one sunrise uses, and it is why a moonrise time cannot be worked out with a sunrise formula.

Prayer times in Portsmouth

Seven days from September 27, 2026, computed for Portsmouth, United Kingdom at 50.80 degrees north, 1.09 degrees west, on the clock of Europe/London. The method is Muslim World League (Muslim World League, Mecca), which puts Fajr at 18.0 degrees below the horizon and Isha at 17.0 degrees. Asr uses the Standard shadow ratio of 1, which is the Shafi'i, Maliki and Hanbali position.

Dhuhr is solar noon at Portsmouth, United Kingdom, the instant the Sun crosses the local meridian, so it moves with longitude inside the time zone and with the equation of time through the year rather than sitting at a fixed clock reading. Sunrise and Maghrib are the standard refracted horizon, the same 0.833 degrees every almanac uses. Every figure above is computed from the Sun's position for this exact coordinate; none of it is copied from a table.

Different methods disagree, and that is expected rather than an error. Fajr under ISNA at 15 degrees comes later than Fajr under Egyptian General Authority of Survey at 19.5 degrees, by twenty minutes or more depending on latitude and season. Follow whichever your local mosque follows.

Qibla direction from Portsmouth

From Portsmouth, United Kingdom the qibla is 117.3 degrees on a true compass, which is east-southeast, or 27.3 degrees south of due east. The Kaaba is 4,816 km away, 2,992 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Portsmouth, United Kingdom to 21.4225 degrees north, 39.8262 degrees east, which is the Kaaba inside Masjid al-Haram.

The bearing is measured from true north, not magnetic north. A magnetic compass points at the magnetic pole, and the difference between the two can be anything from nothing to more than twenty degrees depending where you are, so check your compass reading against magnetic declination for Portsmouth, United Kingdom before you use it. A phone compass set to true north, or the shadow of a vertical stick at local solar noon, avoids the problem entirely.
