I agree about summer in DC. And seriously miss summer in CA. (And fall, winter and spring.)
For those thinking of VT or NH, I found it humid there.
My friend is in Ireland now - 85 in Adare and she hasn’t seen a drop of rain all week!! You never know, I guess!
Queenstown, New Zealand. You may get snowed in.
Burlington, VT has been one of the hottest spots in the country in the past few days! 
The thing is no one can predict with a degree of certainty what the weather will be like anywhere a year in advance. This heat wave isn’t typical for this time of year in most places.
“For those thinking of VT or NH, I found it humid there.”
92+ degrees and 78% humidity for 4 straight days with several more of the same to come. Having spent a good chunk of my lifetime in the area, I’ve never experienced a heat wave lasting this long. Sure hope it isn’t the new normal. It sucks.
I remember the occasional southern New England summers where we still used the fireplace in mid-July.
Really, my years in CA weather spoiled me. I remember, as a kid in PA, thinking: in winter, you can eventually wear enough to get warm. In summer, take it all off and it’s still too hot.
@lookingforward, my feelings exactly. It’s why I live in Maine and not Texas!
Our basement is still very cool, so we’re going to sleep down there tonight.
Hawaii is ok, if you avoid the Big Island if you are concerned about volcanic emissions. If it gets too warm for you, go for a swim or go surfing, kayaking, etc.
My DD was in Scotland last week and it was 89! You never know
Add me to the PacNW crowd (west of the Cascades!). The Seattle area is tough to beat in July+August: cool, clear skies, spectacular views in every direction, unbeatable nature, etc. We went there for a week or so in July a few years ago to escape the heat in Hotlanta and it really did the trick.
Another one is Lake Tahoe. It has a very wide daily temperature range (50-80F) and is dry. The cool morning and low humidity makes the rest of the day “crisp”. Fantastic views and, of course, tons of natural activities.
I’ll be in Tahoe in Sept. Your comment reminds me of a summer in Lake Placid, where they joke: two seasons, winter and July. And iirc, July isn’t all that hot.
Movies, mall, restaurants that seat you early and then go home after sundown
Lol. One if my favorite Married with Childten episodes, they set up beach chairs in the grocery store produce section.
Yes, movies.
We seriously considered Iceland for this summer, but had to drop it due to time constraints and it not really fitting into the budget with our other trips.
Since we had to stay inexpensive and short duration, we’ve opted for Mammoth Cave in the near future. (I’ve always wanted to compare it to Carlsbad anyway.) Underground should be quite nice - with AC when we’re above ground if needed.
Oldest son just returned from taking his wife to Yellowstone and the Grand Tetons for their Anniversary. Their (awesome) pics show them in coats with snow in the mountains. If considering early July and if you haven’t been there, it’s worth a consideration. Yellowstone is my most recommended NP with all it has to offer.
Glacier NP is also quite nice and the Road to the Sun there recently opened for the season. We loved it there and Waterton in Canada which is a continuation of the same area. Yellowstone has snow recorded in every month of the year, so yes, weather there can be volatile and some days there we indeed had the whole range—warm T-shirt weather to freezing rain and snow.
Some caves are very humid.
110 right now. No outdoor 4th of July activities for us. This is where heat-seeking missiles wander aimlessly. We leave for Boston/Maine tomorrow. No relief there, either, with the humidity. 
Ireland just had a heat wave, for a few days it was in the eighties.
I’m baking in the Phoenix area not far from @ChoatieMom
From central Arizona, almost anywhere beats the heat, but i’ll take our dry heat over anywhere humid. We’re heading to the national parks of southern Utah in a couple of weeks. It’s around 90 there, but we’ll think we’re beating the heat!
Last year we went to Whistler, BC. Other years, Aspen, CO, Olympic National Park, the Oregon coast, central CA, Yellowstone and Grand Teton (snowed in June) and I’d really like to go to Jasper National Park and Lake Louise up near Calgary but we haven’t made it yet.
I’d also vote for Iceland. Would love to go there one of these days.
San Diego gets an influx of Arizonans (or Zonies, as they’re known) every summer escaping the heat. We live near the coast and it seems like every third license plate is from Arizona. Generally it stays lovely by the coast although it has gone into the 80’s and 90’s since we moved here. Inland is quite hot.
