Weather in Washington DC in May
May in Washington DC is one of the best times to visit, marked by a significant shift in weather as the city transitions from the crisp breezes of spring to the warmer beginnings of summer. During this month, you can expect more consistent warmth than April, but with less humidity than the summer months for exploring the outdoors.
Temperature Ranges
The city sees average daytime highs comfortably sitting around 75°F (24°C), the perfect conditions for walking tours and getting outside. Nighttime brings cooler temperatures, typically dropping to lows around 56°F (13°C), so having a light jacket for evening outings is advisable.
Rainfall
While May weather is generally pleasant, it does come with a moderate amount of rainfall. On average, Washington DC experiences about ten rainy days throughout the month. Be sure to bring a small umbrella, raincoat, or packable poncho just in case.
Sunrise and Sunset
In Washington DC during May, sunrise times gradually get earlier as the month progresses. At the beginning of the month, the sun rises around 6:05 AM. By the end of May, the sunrise time has shifted to approximately 5:45 AM.
The average sunset time in May gradually extends as the month progresses. At the beginning of May, the sun typically sets around 8:00 PM. By the end of the month, though, sunset has moved to about 8:30 PM. This gives visitors and locals alike more time to explore the city’s landmarks and enjoy outdoor activities into the evening.
May Events in Washington DC
In addition to all of the usual sights of Washington DC, consider adding some of the special events of May to your itinerary. These are some of my favorite recommendations from years of exploring the city!
Passport DC: Embassy open Houses
This unique event celebrates international culture, allowing the public to tour various embassies and experience their culture, food, and entertainment. Embassy open houses are typically held the first two Saturdays in May, offering a unique glimpse into the diplomatic community in DC.
Expect long lines, especially if the weather is good; but this is one of my personal favorite events in DC. I’ve even volunteered before!
Flower Mart at the National Cathedral
The Flower Mart is held annually on the first Thursday and Friday of May at the National Cathedral. This event is the largest fundraiser of the All Hallows Guild, the Cathedral’s gardening society, with proceeds dedicated to the upkeep of the gardens and grounds. It features a selection of flower and garden vendors, food stalls, and family-friendly activities, including a historic carousel.
Memorial Day on the National Mall
The end of May marks a significant time for remembrance in Washington DC at monuments and throughout the city. The National Memorial Day parade and concert on the National Mall honor the nation’s veterans and their families. I also like to stop by the war memorials – particularly the Vietnam Memorial – to see the memorial flowers and remembrances that people leave for loved ones.
Memorial Day at Arlington National Cemetery
Memorial Day activities at Arlington National Cemetery are solemn and reflective, honoring those who have served in the U.S. military. Traditionally, the President of the United States delivers an address to commemorate the occasion. A poignant part of the observance is the “Flags In” tradition, where American flags are placed by service members at hundreds of thousands of headstones throughout the cemetery.
Additionally, wreath-laying ceremonies occur at the Tomb of the Unknown Soldier and other memorials, paying tribute to the fallen soldiers and their sacrifices. These ceremonies are key components of the Memorial Day observances held at Arlington each year.

Previously known as Rolling Thunder, this annual motorcycle rally aims to raise awareness of veterans’ issues. Thousands of motorcyclists ride through the streets of DC during Memorial Day weekend as a tribute to POWs and MIAs.
Jazz in the Garden
Starting after Memorial Day, the National Gallery of Art hosts an outdoor summer concert series known as Jazz in the Garden on Fridays. It’s a popular event where locals and tourists alike gather to enjoy live jazz music in the beautiful setting of the Sculpture Garden. Tickets are available via a lottery system. Info here.
Things to Do in May in Washington DC
Take advantage of the late spring weather with these lesser-known local spots and personal favorites.
- Ducklings on the National Mall: May brings a secret DC activity: the time when baby ducklings hatch! You can find them in the Lincoln Memorial Reflecting Pool, Constitution Gardens, and other parks in the city.
- Picnic on the National Mall or Gravelly Point: Pack a lunch or grab take-out and relax with a picnic on the National Mall – I’ve done this and was the envy of every passerby! Or head to Gravelly Point to watch airplanes take off and land at nearby Reagan National Airport.
- Relax in the Enid A. Haupt Garden: This garden, located at the Smithsonian Castle on the National Mall, is a great spot to catch a break from the city’s bustle. With flowers that bloom throughout the spring and summer, it’s an ideal place for a quick rest in between visiting the nearby museums.
- Visit Arlington Cemetery for late-blooming cherry trees: If you visit in early May, you might be in time for late-blooming cherry trees in Arlington Cemetery. Tram tours are a great way to see the sprawling cemetery and learn about its history. (Note that there is a mandatory ID check at entrances for all visitors over 16 as part of the cemetery’s security procedures.)
- Shop in Georgetown or Old Town Alexandria: Enjoy a day of shopping along the historic streets of Georgetown or browse the waterfront stores in Old Town Alexandria, both known for charming scenery, independent boutiques, and national retailers.
- Visit the National Arboretum: Keep an eye out for azaleas and other late-spring blooming flowers at the National Arboretum. Be sure to get photos with the iconic Capitol Columns, remnants of the original U.S. Capitol building.
- Discover Dumbarton Oaks: I love Dumbarton Oaks, a historic estate in Georgetown with an art museum and a research library, surrounded by beautifully landscaped, expansive gardens. Advance tickets are required for the very-popular gardens from March 15 – October 31. Info here.
- Tour Tudor Place in Georgetown: Near Dumbarton Oaks is Tudor Place, a neoclassical mansion once owned by descendants of Martha Washington. Guided tours generally run on the hour, including the gardens and historic rooms with antiques, some of which belonged to the Washington – Custis family. Reservations are recommended. Tudor Place was designed by William Thorton, who was also the architect of the U.S. Capitol and Octagon House. Info here.
- Take a nighttime tour of the monuments: My favorite time to visit the monuments is at night – when the air is cooler, crowds are less, and monuments are dramatically illuminated. Keep an eye out for impromptu concerts by visiting choral groups at the Lincoln Memorial steps. The World War II Memorial and its fountains are especially nice at night.
- Tour the Bishop’s Garden and the National Cathedral: Take a guided tour of the Gothic-style National Cathedral and wander through its adjoining Bishop’s Garden, with flowers that bloom from spring through summer.
- Have a drink or meal at a rooftop bar and outdoor patio: Savor the cityscape from a rooftop bar for happy hour: the VUE Rooftop at the Hotel Washington has the best views of the National Mall. Or have a leisurely meal at one of the city’s many restaurants with patio dining. (Bonus if it’s brunch, an unofficial pastime of DC!)
- Get out in nature with a hike: Venture into nature on one of DC’s trails, such as Rock Creek Woods, the Western Ridge Trail, or the paths in Theodore Roosevelt Island.
- Visit a winery: Drive out to Loudoun County to explore wineries like Stone Tower Winery or Bluemont Vineyard, both offering tastings and panoramic views of Virginia’s countryside.
- Go for a morning run at the National Mall: If you stay near the Mall, you might want to wake up early for a morning run along with the many locals who follow the routes here each day! Bonus: the Lincoln Memorial is my go-to spot in the city for sunrise.
- Take a C&O Canal boat tour or Georgetown walking tour: A boat ride on the C&O Canal begins in Georgetown and demonstrates the historic lock system along a scenic stretch of the canal. Note that the boat tours are currently on hiatus while restoration work is done on the canal; but walking tours should begin.
Of course, all of the usual sights are perfect for May also, including the city’s Smithsonian museums and institutions which number 20 in all, including the National Zoo! But I think it’s nice to include some special outdoor activities in your itinerary if you visit during the month of May.
