City comparison

Lisbon vs Porto

Rent, visas and flight costs rank these two the same way for everybody. The variable that is different for you is the one nobody has been able to check, until you can.

In short

Neither city is better. A place has no fixed character, it has a relationship with one particular birth chart, and Lisbon and Porto rank differently for people born days apart. What can be compared without knowing your birth moment is what each place is: how far north it sits, how much of the sky rises and sets there, and how many of the forty lines can reach it at all. That is what the rest of this page does.

What each place is

These figures come from the two cities’ positions and nothing else, so they are the same whoever is reading. Both are the starting point for a reading, never the reading itself.

Lisbon, Portugal

Position
38.72°N, 9.1°W
temperate latitudes, northern hemisphere

Europe/Lisbon
Clocks run 37 minutes ahead of the local sun
Lines that can reach it
All forty
A body more than 51.3° from the celestial equator never rises or sets here
Longest day
14 hours 43 minutes
At the summer solstice

in the temperate middle latitudes, where the difference between a summer and a winter day is something you plan around

How the two differ, measurably

Three differences that hold for every reader, and one that does not hold for any two readers alike.

Distance, in the units a line is measured in

They are 274 km apart, which is 2.5° of great-circle distance. A planetary line counts as reaching a place within about two degrees, so two cities 2.5° apart are far enough apart that a line landing on one tells you nothing at all about the other. They have to be read separately.

How much of the sky rises and sets

Lisbon sits at 38.72°N and Porto at 41.15°N a gap of 2.4°. That is not a detail of climate; it decides which lines can exist. At Lisbon a body further than 51.3° from the celestial equator never rises or sets, and at Porto the limit is 48.9°. Both are low enough that all ten bodies clear it, so the full set of forty lines is drawable at each.

What the clock is doing to the sun

0.5° of longitude separates them, about 0.0 hours of solar time. Against their own clocks, midday in Lisbon arrives 37 minutes after the sun is actually overhead, and in Porto, 34 minutes after. This has no bearing on a reading, your lines come from where you were born, not where you are standing, but it is exactly the kind of difference that makes a birth time recorded in the wrong zone move every line on a map.

And the one that is yours alone

Everything above is true for everybody. Which of these two places asks more of you, gives more back, or is simply quiet ground is a function of one arrangement of the sky that has never repeated, the one over you at birth. Most of the world is quiet ground for most charts, and if that is the answer here we say so rather than reaching for the nearest thing.

Questions

Questions people ask

Where the honest answer is unhelpful to us, it is still the one printed.

  1. Is Lisbon or Porto the better city?

    Neither, in general, and any page that answers that question without knowing when you were born is describing something that does not exist. A city has no fixed character; it has a relationship with one particular birth chart. Lisbon may sit almost exactly on a line of yours while Porto is nowhere near anything, or the reverse, or, most commonly, both may be quiet ground for you. The reading at the top of this site works that out in about a minute, free, on your own device.

  2. How far apart are Lisbon and Porto?

    274 km, great-circle. In the units this product measures proximity in that is 2.5° of orb, which matters because a planetary line is only considered to reach a place within about 2°. Two cities 2.5° apart are far enough apart that a line reaching one says nothing about the other.

  3. Can all forty lines reach both cities?

    Yes. Every one of the ten bodies rises and sets at both latitudes, so all forty lines are drawable at Lisbon and at Porto.

  4. Does the time difference between them matter for a reading?

    Not for the reading itself, the lines come from where you were BORN, not from where you are standing. It matters for the birth moment: Lisbon and Porto are 0.5° of longitude apart, about 0.0 hours of solar time, so if you were born in one and entered the other's time zone by mistake, every line on your map would move by roughly 59 kilometres.
