City allergy guide
Newark allergy profile
Today's risk+
Newark sits in the North Jersey and New York metro allergy zone, where spring tree pollen is usually the main early-season issue before grass pollen rises around parks, school fields, and landscaped spaces. Later in the year, ragweed and other weeds across the broader region become more important.
Because Newark is dense and heavily traveled, pollen exposure can feel different near open park areas, tree-lined streets, transit stops, parking lots, and heavily paved corridors. Heat retained by streets and buildings can also push some plants earlier than cooler nearby areas.
Newark's guide sections below focus on recurring local exposure patterns. Today's very low Elm reading is the live risk signal, while the seasonal and neighborhood notes explain where exposure can still differ during normal routines.
Seasonal guide+
January-February
Lowest outdoor pollen; indoor triggers matter
Outdoor pollen is usually limited, but dust, pets, indoor mold, and warm spells can still affect sensitive residents.
March-May
Tree pollen ramp-up and peak
Maple, oak, birch, and other tree pollen often drive the strongest spring symptoms across North Jersey.
May-July
Grass pollen season
Lawns, athletic fields, parks, and roadside grasses become more relevant during warm, dry stretches.
August-October
Ragweed and late-season weeds
Ragweed can spread widely across the metro region until colder weather and frost reduce activity.
Treatment and planning tips+
Commutes
Use sunglasses on windy walks, keep car windows closed, and consider rinsing your face after long outdoor transit waits.
Exercise
Choose lower-risk windows when possible, especially after rain or later in the evening on high tree-pollen days.
Home air
Keep windows closed during high-pollen periods and use HVAC filtration if pollen triggers symptoms indoors.
