Best Time to Visit Washington DC: A 5-Step Guide

Step 1: Find the best time to visit Washington DC by weather

The best time to visit Washington DC for weather is April, May, September or October. NOAA's 1991 to 2020 climate normals for Reagan National Airport show average highs of 68°F in April, 77°F in May, 81°F in September and 69°F in October. The NOAA climate normals are the long-run averages, not a forecast.

April, May, September and October suit a day of walking. The National Mall is big, and you cover a lot of ground on foot. Mild air makes that easy.

Rain does not help you choose. It falls in every month. The driest month is February with 2.6 inches, and the wettest is July with 4.3 inches.

For a full table of highs, lows and rain, see the weather washington dc monthly guide.

Key Takeaway For easy walking weather, pick April, May, September or October, when average highs run from 68°F to 81°F.

Step 2: Time your trip for the cherry blossoms

The best time to see the cherry blossoms in DC is late March to early April. The National Park Service says peak bloom most often falls between the last week of March and the first week of April. It defines peak bloom as the day 70% of the Yoshino cherry blossoms are open.

The dates move from year to year. Peak bloom came on March 26 in 2026. In the seven years from 2020 to 2026, the NPS table shows it falling between March 17 and March 28. In 1990 it came as early as March 15, and in 1958 as late as April 18.

The bloom is short. The NPS says the trees bloom for several days. Cool, calm weather can make it last longer, and a rainy, windy day can end it fast. A late frost can stop the trees from blooming at all.

You cannot lock in the date far ahead. The NPS says forecasting peak bloom more than 10 days out is almost impossible. Pick a window of several days around the first week of April, and choose refundable bookings.

The festival around the bloom has fixed dates. The National Cherry Blossom Festival runs March 20 to April 11 in 2027. Its calendar lists the parade on April 10 and the Japanese street festival on April 10 and 11.

The trees are free to see, so you can do this on your own. A tour is worth it if you want a guide, the story of the 1912 tree gift from Japan and the best photo spots. It does not add a ticket, because the memorials are free to enter. Things to Do in Washington DC's count of GetYourGuide listings in October 2026 found 7 cherry blossom tours, from €35 to €79 per person. Read more on our page for cherry blossoms dc. The cost study checked hotel prices only for December and June, so it does not price late March or early April. Check your own dates.

The cherry blossom bus tour runs 4 hours and is from €53 per person, with a 4.6 rating from 70 reviews. USA Guided Tours runs it, and it shows free cancellation. It meets at 701 Pennsylvania Avenue NW, and the group is up to 30 people. The listing includes a guide, a climate-controlled bus and a guided walk around the Tidal Basin. Entrance fees and tips are not included.

The Tidal Basin cherry blossom walk runs 2 hours and is from €35 per person, with a 5.0 rating, but from only 5 reviews. It is run by DC by Foot and shows free cancellation. It meets at the D.C. War Memorial and visits the Martin Luther King Jr., FDR and Jefferson memorials. It is a small group, and the listing gives no number. Tips are not included.

Pro Tip Book a blossom tour with free cancellation and keep a spare day, because the NPS says no one can forecast peak bloom more than 10 days ahead.

Step 3: Plan around the summer heat

July is the hottest month in DC, with an average high of 90°F and an average low of 72°F. August is close behind, with an average high of 88°F. June averages 85°F. These are the NOAA normals for Reagan National Airport.

Humidity makes it feel hotter. The National Weather Service says heat and high humidity can quickly cause heat illness. Its chart gives an example: 95°F with 50% humidity feels like 107°F. It also says full sunshine can add up to 15 degrees to the heat index.

The city holds the heat. The NWS says large cities such as Washington are at risk for many heat deaths, and that alert limits can be lower in the first heat event of the year. A Heat Advisory means a heat index of 105 or higher.

So plan summer days in two parts. Walk the Mall early, rest indoors from noon, and go out again in the evening. The NPS says the National Mall and Memorial Parks are open 24 hours a day, and calls the early evening and morning hours tranquil times to visit.

The water and the night are two cooler options. The Potomac River sightseeing cruise lasts 45 minutes and is from €27 per person, with a 4.2 rating from 214 reviews. CapitolRiverCruises runs it from Georgetown, at 3050 Water St NW, and the group is up to 60 people. Wheelchair users are not eligible. Food and drink are not included, and tips are not either.

The Monuments by Moonlight trolley tour runs 2.5 hours and is from €54 per person, with a 4.6 rating from 1,619 reviews. It is run by Historic Tours of America and has two meeting points, depending on the option you choose. The group is up to 50 people. Tips and food are not included.

When you can choose, skip July and August afternoons. The same sights are easier in May or September.

Step 4: Check the hotel price by month

The price of a hotel bed changes a lot by month. In December, a 4-star hotel night in Washington, DC cost a median $150 per room for two, against $316 in June, in the 2026 Washington, DC Travel Cost Study.

The gap is large, so the month changes your budget as well as your weather. If you can take the cold, December has the lowest 4-star price in the study. If you want mild weather, check the hotel price for your own dates before you pick a month.

Where you sleep matters too. For a base that works in any season, the Hilton Garden Inn Washington DC Downtown is on 14th Street NW, 3 blocks from the White House and 1 mile from the National Mall. For a summer trip near Nationals Park, the Thompson Washington DC is 6 minutes from the ballpark. See where to stay for each area.

Step 5: Choose your month and avoid the crowds

Pick the month from your top goal, then adjust for crowds. The table below matches each goal to a month.

No official page publishes crowd counts for DC by month, so this guide cannot name the quietest month. It only reports what the official pages show. The festival runs March 20 to April 11 in 2027, with the parade on April 10 and the Japanese street festival on April 10 and 11, so expect more people on those days. The Mall is open 24 hours a day, so go at dawn or after dinner and the sights are calmer.

Winter works for indoor sights. The museums and the Capitol are indoors, and the Capitol Visitor Center says all its tours, programs and activities are free. Plan those for the coldest hours.

For the open-air sights, the National Mall and monuments page covers the walk. Go in the cool part of the day in any season.

One honest limit. This guide cannot name the bloom date for your trip. If the blossoms are the only reason you are coming, no month is a sure thing, because a warm spell or a late frost can move or cut the bloom. Plan the rest of the trip so it still works without the trees.

The best month is the one that suits what you want to see, not the one with the nicest average.
