Washington DC Holidays

In a vibrant city like Washington, D.C., vacations are ideal any time of year. The city is abuzz during Cherry Blossom Festival (spring), 4th of July, and when Congress is in session (mid-September through Thanksgiving, and mid-January to June).For fewer crowds and lower hotel rates, travel between late August and early September, or after Thanksgiving into mid-January.

Weather-wise, winters can be erratic (flurries, ice storms), while falls are warm, crisp and colorful. Summers are hot and humid, but hotel rates are low from early July (after the 4th) through August. Spring showers are common, but come May D.C. comes alive with sunshine and greenery.
