Hot outside and cold inside? Packing question

Question

I know it will be warm next week in DC but are the buildings cold inside with the AC? In some places like Florida you have to wear long sleeves or sweaters inside when it’s 90 outside. Is this true in DC too? Trying to do my packing.

Thanks

Answer

Yes, it is definitely something to plan for when visiting DC in the summer. Outdoor temperatures can easily reach the 80s or 90s°F, but most indoor spaces like museums, restaurants, government buildings, hotels, and shops tend to have strong air conditioning. It can feel quite chilly inside compared to the heat outside.

Here are some tips to help with packing and staying comfortable:

Bring a light sweater or long-sleeve shirt for indoor spaces. Even a thin cardigan or a packable jacket can make a big difference.
Consider layering. For example, a t-shirt with a light layer you can put on or take off depending on where you are.
Some places, especially museums or government offices, can be very cold, sometimes even cooler than typical indoor AC settings, so err on the side of bringing something warm.
If you’re dining in restaurants or walking into cafes, having a light layer is convenient since some eateries blast AC for comfort or energy savings.
For outdoor excursions like walking the National Mall, memorials, or neighborhoods, wear breathable clothing and sun protection, since the sun can be intense.

In short, DC is similar to other major cities in that indoor spaces are often much cooler than outside. Packing a small, portable layer for indoors will keep you comfortable throughout your sightseeing.
