Western Maryland

The sugar maples in the lower elevations of the Wallman area of Potomac State forest are already displaying vibrant yellow leaves, while the red maples are casting a ruby glow, outlining a wetland area on Snaggy Mountain in Garrett State Forest. Black gums in the higher elevations of Piney Mountain in the Garrett State Forest are displaying a range of autumnal hues, from bold scarlets to warm oranges and yellows.

Northern/Central Maryland

We are still seeing lots of green in Patapsco Valley State Park, which is normal for this time of year. Many of our park visitors are enjoying the last gifts of summer – warmer waterways, shady trails, and abundant scenery.

Southern Maryland

Summer and fall are comingling in southern Maryland, with minimal overall leaf color change. The black gums and yellow poplars are beginning to reveal their fall colors, mixing in with their forest neighbors still holding on to their summer blooms.

Fall Recreation Spotlight

  • Monarchs and Milkweed at Merkle, Merkle Wildlife Center, Saturday, September 24, 2022
    10 a.m. – 2 p.m.
    The Maryland Department of Natural Resources invites everyone to Merkle Wildlife Sanctuary to celebrate the fall migration of the monarch butterfly. In Maryland, monarchs begin to migrate south in early fall (September and October), many of them flying all the way to central Mexico where they overwinter in a single mountain forest.
    Merkle Wildlife Sanctuary is a 1,900-acre natural resource management area in Prince George’s County.

Watch the sky

The September equinox occurs on Thursday, September 22 at 9:04 p.m. EDT. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of fall in the Northern Hemisphere.

The “Summer Triangle” asterism of Vega, Altair, and Deneb is still visible in the September sky. Also, Jupiter will make its closest approach to Earth since 1963 on September 26, so sky watchers will have a chance to see it in its full glory—as well as four of its largest moons.
