Autumn colour will sweep through the north-eastern United States over the next six weeks, with the best time to see peak fall foliage varying sharply between mountain regions, inland valleys and the Atlantic coast.
The display is expected to begin in the highest elevations in early October before moving through lower-lying areas and reaching New York City, Washington DC and coastal communities in November.
When to see peak fall foliage across the north-east
In New York, the season generally starts in the Adirondacks, Catskills and other upstate mountain areas from early to mid-October. Lower elevations should reach their best colour later in the month, followed by the suburbs around New York City in early November.
New York City itself is likely to see its strongest display around the middle of November, although individual parks and neighbourhoods can change at slightly different times depending on local conditions.
Pennsylvania’s foliage season follows a similar pattern, beginning in the northern counties and higher ground between October 11 and 18. Colour then spreads through the central mountains and western parts of the state from October 19 to 31.
The south-eastern counties, including areas around Philadelphia, Lancaster and Delaware County, are expected to reach peak colour between November 1 and 9. Pennsylvania’s Department of Conservation and Natural Resources publishes weekly reports during the season, with updates released on Thursdays.
In New Jersey, the northern counties – including Sussex, Warren, Morris and Bergen – are expected to turn first, from early to mid-October. Central areas should follow around the middle of the month, while the southern and coastal counties are more likely to reach peak colour between mid and late October.
The influence of the Atlantic means the season arrives later in Maryland and Delaware. Northern Maryland is expected to see the brightest colours in late October, with inland areas of both states following in early November.
Coastal locations, including Delaware’s beaches and Baltimore’s Inner Harbor, could remain colourful until the middle of November, although wind and rain may shorten the display.
Virginia offers one of the longest viewing windows. The highest mountains in the south-west and the Alleghenies should reach peak colour in early to mid-October, followed by the Shenandoah Valley and wider mountain regions later in the month.
Central and northern Virginia are expected to peak from mid to late October, while coastal areas may not reach their best until late October or early November. Washington DC is likely to see its strongest colours in early to mid-November, though dry conditions could reduce the length of the peak period.
Virginia’s tourism corporation has launched a new online autumn resource in partnership with the state’s forestry and conservation agencies and the US Forest Service. It includes regional foliage maps, scenic driving routes and updates intended to help visitors plan around the short peak season.
Weather can alter the timetable from one year to the next. Cool nights and sunny days generally produce the most vivid colours, while strong winds, heavy rain, early frost or prolonged dry conditions can bring leaves down before they reach their fullest display.
Visitors planning trips are advised to check the latest reports from state parks and forestry agencies before travelling, particularly during the final week of October and the first half of November when the peak moves rapidly through the region.
