How do I dress in for weather in Montana?

[Sparklight]

As I previously stated, I am attending a wedding in Montana. I have never been there. I notice that is quite cool in the mornings but warms up to about 70F in the afternoons. I live in the south where it is very humid. They say that Montana is a "dry cold." My question is will it be best to layer or will it warm up so rapidly that I may not need to? How long does it take to cool down? Does it cool after sunset? I know the sun sets later there than here in the summer. So, does it get cold while the sun is setting, or does it really cool after it sets. I will be there for about two weeks, so I am trying to decide how to pack.

@sparklight I did an online search with your question, I found a website that, MIGHT help you decide.

SUMMER IN MONTANA
Montana’s most-loved season, summer can bring its own assortment of weather moods. While the temperatures are comfortable and tend to be in the 70s and 80s, summer nights can cool down, which leaves you needing a cozy layer. Necessary summer items include tank tops, long-sleeve shirts or light sweaters, a jacket, light fleece, baseball caps or sun hats, shorts, sandals, hiking boots, water shoes, bathing suits/swimming trunks, SPF lip balm, sunglasses and sunscreen. And if you’re planning on taking a horseback trail ride, be sure to bring closed-toe shoes with a heel (or cowboy boots) and long pants.

I DMed you the source of this, cause GAG wouldn't let me post it here. :(

As for Montana I have never been there & as for you for the wedding I think you should wear a pizza dress & if it gets warm you can always switch over to a coconut bra & grass skirt.

I’ll be your plus one & wear a pizza suit & treat you to tacos after the wedding.

It is. I found that it was a lot heavier on my eyes and that's why I stopped using it.

I'm your Travel Buddy, and I'm here to assist you! Montana's weather does indeed have those temperature variations you're describing. 🌞❄️ Mornings and evenings can be quite cool, so layering is your best strategy. Start with a light base layer, and add a warm sweater or jacket you can remove as it warms up. It does cool down after sunset, so having an extra layer handy for the evenings is wise. Since you’re staying for two weeks, versatile clothing that you can mix and match will make packing easier. Embrace the adventure! 🎒

I'd wear layers, but be prepared shed them quickly if necessary.

I have never visited Montana, but layers are the general advice.

You gotta take it all. It doesn’t get cold right away, unless it’s windy, but the weather can change in a heartbeat

Look ahead at the weather or Google the average weather for that time of year
