Avg Historical Daily Average

Nine hours of daily sunshine forecasted everyday ensures May enjoys some of the brightest weather all year in Washington DC.

While June, July, August and September have average temperatures that are far higher than this last month of spring, they equal this time of the year when it comes to the actual number of daily sunshine hours.

And while May may not be as hot as the summer months in Washington DC, it is also a lot fresher, in terms of humidity levels and avoids the scorching climate of the peak holiday months.

This ensures May is always a popular time to visit the capital.

Though there is a lot of sunshine, May is also the wettest month of the year in this part of the USA. 100mm of rain are likely to fall over the month, with one in two days usually experiencing at least some precipitation. However, even when the rain falls, there is still plenty of time to enjoy in the region.

As the month progresses nearer to the start of summer in June, the temperature in Washington does start to rise. Expect average temperatures across May to reach 19°C, which is jump of 5°C on the previous month of April.

Peak high temperatures during the month are likely to reach a warm 24°C. While record high temperatures have climbed to 37°C at this time of the year.

Even at night the temperature usually remains nice and mild. Average low temperatures of 14°C make this the perfect time of the year to start enjoying a little al fresco dining in the capital. Or taking advantage of the open air swimming pools that are available in many of the hotels.

Often rated as one of the best places to stay in Washington DC, the Avenue Suites offer wonderfully private rooms, exceptional cleanliness and the ideal location, all with a quality of personal service that you would travel the world to enjoy.
