We will be in Edinburgh and St Andrews mid September. I have been checking the daily temperatures, but that does not tell me what sort of clothes to pack. Will mid September in Scotland translate to fall clothes--or more toward winter? Thanks for any help.

Fall clothes will suffice, but make sure to layer (tank/T-shirt, long-sleeved shirt/sweater). Definitely have a waterproof coat and/or umbrella. Scarves for women are a great fashionable accessory that keeps your neck warm.

Fall clothes should be fine. I would doubt that the temperature will drop very low. Pack for layers as there is always the chance of a mild September!

I would take a mildly heavy jacket. You can get very cold temps in September and coupled with the wind....it can be uncomfortable.

It was 24 degrees here yesterday and it's 10 today. Come prepared for anything; and layer, layer, layer.

I second the advice about layering. I've travelled a lot in Scotland over several years, generally in very early October.

You can be very lucky with glorious sunshine but I have never been as cold as I was at Edinburgh Castle. The wind chill factor can be severe.

I would recommend a mid weight jacket, plus layers. I think any transition season can be very unreliable and it's also amazing how fast the weather changes even in a few weeks.I'd take the jacket even if you have to carry it as it's definately worth the comfort!

We were in Edinburgh May 24 this year, one day I was in a t-shirt, the next I was walking around the castle freezing in the pouring rain.
Take a waterproof hooded jacket since of course my slight umbrella turned inside out!
My husband took his leather winter jacket with zip out lining for the trip and I envied him the whole time. Wished I'd had my leather gloves on the firth too.
Comfortable boots are cool looking and a great addition. Could have used them at Roslyn Chapel ( half hr south of Edinburgh) where the cold of the stone floor came through the bottom of my leather shoes!

This is a perfect reason to buy a good Scotland sweater. You were wondering what to bring back home.

Have a look at these sweaters.

I'm drooling wanting to have one myself.

RAINCOAT. UMBRELLA. WATERPROOF SHOES.

It probably won;t be cold enough for a winter coat but do bring lots of layering options. We were there once in July (it had been almost 90 in London 4 days before) and it was in the high 40's, raining and windy. I wore one of everything I had (tee shirt, long-sleeve blouse, sweater and raincoat).

Many of the locals had hats and gloves - and didn't seem surprised by the weather.

I've travelled in Scotland for 10 weeks over various Augusts/Septembers. I always bring a mid weight fleece and a goretex rain shell, which I wear either singly or together. I usually bring some cardigan sweaters as well.
