Which side is the sun on?

Posted 12th JanEdited by:"deeky"
Ok, here's one for you. Imagine you were sailing across The North Pacific Ocean from Vancouver to Tokyo. On a boat. In September. Which side of the boat would the sun be shining on for most of the day? Is there anywhere you can map the route of the sun on any given date? I know the sun rises in the east and sets in the west so I'm thinking the port side of the boat would get the sun during the day. Yes? Or are there details I would need to take into account?

Never go where the sun don't shine.

When you’re on the northern hemisphere, Sun is always South. In this case- left side.

I suppose I just wanted confirmation. I've been wrong before. Can't remember the last time but I'm sure I must have been
If the moon can be plotted down to about 10 mins accuracy for any map grid ref point for weeks ahead. I'm no Brian Cox, but if there is publicly available future tides in/out peak graph data for any location on places such as BBC weather website section, then I would assume that also the sun plotting for map coordinates must also be publicly available?

I think something like this but I don't know how to work it

Left side of the boat, if it is on any other side you're probably going the wrong way!

Why the need for the knowledge of the sun. Is the sun desired, or not desired in this instance? Is this going to be a solar powered boat, or is more the issue of sun burn, heat exhaustion etc?

I'm thinking of taking a cruise on that particular route and would like to book a balcony cabin on the sunny side of the ship. It's a one-way repositioning cruise which involves about 8 days at sea so wouldn't want my balcony to be in the shade for the duration of the cruise.
Think POSH Port Out Starboard Home. Sailing from England to India back in the day to see the land on the way out you had, a port side cabin. The return you went starboard as it thought it was a better view to see the land rather than the boring sea. As you are going the opposite way and you want the sun I assume the same applies?
Meh.
On the sunny side of the street
The Sun is roughly over the equator. It’s at its highest around noon local time.
Thanks for your input everyone. I think it's established that the sun will be on the left
In the northern hemisphere, the sun rises east/sets west, but moves more northerly in the Winter and transits southerley in the summer. So, generally, in Winter at mid latitudes the sun rises North East and sets North West.
You can use the calc here suncalc.org/ to set the date and time and the little grey circle is the position of the sun.
The highest northern latitude where the sun can be directly overhead is the tropic of cancer, which goes through Taiwan and the tip of Baja California.

Anything north of that and the sun is always south of you at noon.

I never knew that "folk etymology" of the word Posh until last week. Was on telly but can't remember what it was I was watching.
Oh wait, you’re having another holiday ?

1)its alright for some

2)train drivers get paid more than me

3)remember your last cruise ( June .?) hope she’s walking again

Not true


Even in the UK, in May - July, the sun is to the north in the early morning and late evening


Deeky, this app is excellent

I believe you have that all the wrong way around. In winter, the sun sets in the south west and rises in the south east

Which little grey circle? Do you mean the upturned crescent shape?

I dragged it to half way across the Pacific and ended up with this on the SunCalc site. Am I right in thinking that I've arrowed the path of the sun? If so, that looks perfect, sun on the balcony all day

Thought it was very intuitive

You can change the date on the HOME View to see sunrise sunset etc info

You can see the sun and moon transit on the 3D view by moving the time bar at the bottom.

Nice small widget too showing sunrise and sunset times for the current day

The trouble is, there is no location in the middle of the Pacific and when I input what I think are the co-ordinates, nothing happens.

So Tokyo is in the centre of the compass? Can you do that for a point halfway between Vancouver and Tokyo?

So would you agree that this is roughly the sun's orbit for that location?
