Baltimore’s Halloween forecast favors outdoor plans: mostly sunny skies, light north winds and an afternoon high near 63 degrees. Saturday night turns cooler, with temperatures dropping into the 40s, but partly cloudy skies and little wind are expected.
Sunny Halloween, Chilly After Dark
Temperatures start Saturday in the upper 40s, then rise through the 50s to the low 60s in the afternoon. North winds of about 5 to 6 mph will add a crisp feel, with no rain expected.
Saturday night’s forecast calls for partly cloudy skies, a low around 46 and south winds from calm to 3 mph. A jacket may come in handy for evening Halloween plans as temperatures fall.
Warm-Up Arrives Next Week
The mild trend continues Sunday, with mostly cloudy skies, a high near 64 and an overnight low around 46. Monday is forecast to be mostly sunny with a high near 67; Tuesday should bring partly sunny skies and a high around 70, according to the National Weather Service.
Wednesday’s high could reach about 73, the warmest reading in this stretch. Clouds are expected to build, with rain chances increasing overnight; showers may develop after 7 p.m. Wednesday. Showers and thunderstorms are possible Thursday as temperatures remain unusually mild for early November.
How the Warm-Up Compares With Normal
For an early-November benchmark, the normal high at BWI is 63°F on Nov. 1 and 62°F on Nov. 2, according to the National Weather Service Baltimore/Washington Weather Forecast Office. Wednesday’s forecast high near 73°F is about 10°F above those normal highs.
November Climate Context
For a broader seasonal comparison, a typical Baltimore November has a high of 57.3 degrees, a low of 36.5 degrees and 3.13 inches of precipitation, according to WMAR-2 News, citing National Weather Service normals. Those monthly averages put the forecast warm spell and late-week rain chances in context.
The longer-term climate record offers additional context, but does not explain this particular forecast: NOAA’s Maryland and District of Columbia State Climate Summaries report that Maryland’s annual average temperature has increased more than 2.5°F since the beginning of the 20th century.
Rain Chances Continue Into Friday
The unsettled pattern is expected to continue Thursday night, when showers and thunderstorms have a 50% chance of developing and the low is forecast near 59. Friday should be partly sunny, with scattered showers still possible and a high around 71.
A Small Craft Advisory remains in effect for nearby Maryland waters through 9 a.m. Saturday, with gusty winds possible early and conditions expected to ease later in the day. The National Weather Service Baltimore/Washington office defines a Small Craft Advisory wind headline as 18-33 knots; the marine notice applies to boaters, not the land forecast. No other hazardous weather is expected through Tuesday.
