The weather station at BWI recorded 1.7 inches of snow, which broke a 110 year old record for the date set in 1908. Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. The earliest sunrise is at 5:39 AM on June 13, and the latest sunrise is 1 hour, 54 minutes later at 7:33 AM on October 31. The horizontal axis is the day of the year, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. The most snow falls during the 31 days centered around February 5, with an average total liquid-equivalent accumulation of 0.6 inches. The earliest sunset is at 4:43 PM on December 7, and the latest sunset is 3 hours, 54 minutes later at 8:37 PM on June 27. The wetter season lasts 4.4 months, from April 11 to August 23, with a greater than 30% chance of a given day being a wet day. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. A climate graph showing rainfall, temperatures and normals. The cold season lasts for 3.3 months, from November 30 to March 7, with an average daily high temperature below 52°F. Compare the charts and see my notes below: You may recall 2003, 1996, and or 1979. A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. 1996 END of Year: 0.3″ in November and 0.2″ in December. The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F.

The brightest day of the year is June 22, with an average of 6.9 kWh. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). support@__remove_this_part__weatherspark.com. : Average precipitation in inch - DP : Days with precipitation - Sun : Hours of sunshine, Monthly averages BaltimoreLongitude: -76.6122, Latitude: 39.2904Average weather Baltimore, MD - 21205.

Will this Happy Fall bring a snowy winter? The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The brighter period of the year lasts for 3.8 months, from April 27 to August 22, with an average daily incident shortwave energy per square meter above 5.9 kWh.
Based on this score, the best time of year to visit Baltimore for hot-weather activities is from late June to early September, with a peak score in the second week of August. For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. So there is some hope. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end. The smallest chance of a wet day is 21% on October 19. Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more. The least muggy day of the year is February 11, when muggy conditions are essentially unheard of. The least rain falls around January 30, with an average total accumulation of 2.1 inches. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. Lower dew points feel drier and higher dew points feel more humid. We just had our record November storm, and a good start to winter. That’s more than double, in some cases nearly triple our average of 21 inches in a season! The drier season lasts 7.6 months, from August 23 to April 11.
