Best Time to Visit New Jersey: A Month-by-Month Guide

Quick answer

September and May are the best months to visit New Jersey. September offers warm Atlantic Ocean temperatures (approx. 21°C/70°F) and lower hotel rates after Labor Day, while May provides peak bloom in the Essex County Cherry Blossom Collection with moderate temperatures. Avoid January and February due to freezing winds and potential snow that disrupts NJ Transit rail services; July and August are the most expensive months with high humidity and heavy crowds at Point Pleasant and Ocean City.

January

January is the coldest month in New Jersey. In Newark and Jersey City, biting winds off the Hudson River make the approximate 4°C (39°F) high feel significantly lower. Snowfall is common, often accumulating to 20cm (8 inches) or more in the northern Highlands. Rainfall is frequent but often turns to ice, making pavements in urban centres like Hoboken treacherous. Humidity is low, leading to very dry air indoors.

Crowds are at their annual minimum, except for ski resorts like Mountain Creek in Vernon. Hotel prices are at their lowest point of the year, often 40-50% cheaper than summer rates. Flights into Newark Liberty International (EWR) are generally inexpensive outside of New Year's Day. Key events include the Wildwood Ice Blast (mid-January). Families may find the weather restrictive as outdoor walking is difficult for small children. A 2-day trip for indoor shopping at American Dream mall is sufficient. Pack thermal base layers, a heavy down coat, waterproof boots, and gloves.

Should you go in January? Skip it, because the grey skies and freezing temperatures limit outdoor activities.

February

February remains deeply cold with average lows of -3°C (27°F). It is often the month with the heaviest snowstorms. Day-to-day weather involves frequent overcast skies and "Nor'easters" that can bring heavy rain or snow to the coast. Atlantic City boardwalk is largely empty and cold.

Crowd levels are low, providing easy access to restaurants in Montclair or Morristown without reservations. Hotel and flight prices remain low. The New Jersey State Boat Show (mid-February) in Edison is a notable event. There are no significant natural blooms; trees are dormant. Families should focus on indoor attractions like the Liberty Science Center. A 3-day weekend is plenty. Pack heavy winter gear and ice-melt salt if driving.

Should you go in February? Only if you are visiting for indoor entertainment or discounted Atlantic City casinos.

March

March is a transitional month known as "mud season." Temperatures fluctuate wildly between 2°C and 15°C (35°F-59°F). Late-season snowstorms are possible, but rain (approx. 105mm) is more common. Humidity begins to rise slightly.

Crowds remain thin until the St. Patrick’s Day parades, particularly in Newark and Belmar (mid-March), which draw tens of thousands. Hotel prices start to creep up in late March. Flights remain moderately priced. You might see early crocuses or snowdrops, but the landscape is mostly brown. This month is difficult for families due to the "four seasons in one day" volatility. A 3-day trip is recommended. Pack layers: a light jacket over a sweater and waterproof shoes.

Should you go in March? Only if you are attending specific Irish heritage events.

April

April brings the first consistent signs of spring. Highs average 16°C (61°F). The weather is notoriously rainy, with frequent showers that can last all day. Humidity is moderate. The Essex County Cherry Blossom Festival at Branch Brook Park in Newark (mid-April) features over 5,000 trees, surpassing Washington D.C. in quantity.

Crowd levels increase around parks and gardens. Hotel prices are moderate, though they spike near Newark during the bloom. Flights are mid-range. Spring blooms are the primary natural event. It is a good time for families to visit zoos like Turtle Back Zoo before the summer heat. A 4-day trip allows for rain delays. Pack an umbrella, a trench coat, and comfortable walking shoes.

Should you go in April? Yes, specifically for the cherry blossoms in Newark.

May

May is one of the most pleasant months. Average highs reach 22°C (72°F) with low to moderate humidity. Rainfall is still present but occurs in shorter bursts. The landscape is fully green, and tulips are in bloom at the Holland Ridge Farms (approx. late April to early May).

Crowds are moderate as the Shore prepares for the season, but beaches remain quiet. Hotel prices rise significantly toward Memorial Day weekend (late May), the unofficial start of summer. Flight prices also increase. Migratory birds return, making it a peak time for birdwatching at Cape May. Families will enjoy the mild hiking in the Delaware Water Gap. A 5-day trip is ideal. Pack light layers and sun protection.

Should you go in May? Yes, it is the best month for outdoor activities and gardening enthusiasts.

June

June marks the start of beach season. Temperatures average 27°C (81°F) and humidity begins to feel heavy. The ocean is still cool, around 18°C (64°F), which may be too cold for some swimmers.

Crowds at the Jersey Shore (Asbury Park, Seaside Heights) increase heavily on weekends. Hotel prices are high, especially on Friday and Saturday nights. Flights are expensive. Fireflies begin to appear in suburban gardens in late June. It is excellent for families as schools let out and boardwalk rides open fully. A 7-day trip is standard for a Shore rental. Pack swimwear, shorts, and insect repellent for evening mosquitoes.

Should you go in June? Yes, for the beach atmosphere without July's extreme heat.

July

July is the hottest and most humid month. Highs regularly exceed 30°C (86°F), and heatwaves can push inland temperatures to 37°C (99°F). Thunderstorms are frequent in the late afternoons.

Crowds are at peak levels, particularly at Wildwood and Ocean City. Expect long queues for everything from pizza to parking. Hotel prices are at their annual peak; a basic motel room near the beach can cost $300-$400 USD per night. Flights are very expensive. The New Jersey Festival of Ballooning (late July) in Readington is a major draw. Families should be cautious of the midday heat. A 7-day stay is common. Pack high-SPF sunscreen, light linen clothing, and hydration packs.

Should you go in July? Only if you thrive in hot, high-energy beach environments.

August

August continues the heat of July with average highs of 29°C (84°F), but with even higher humidity levels. The ocean temperature peaks at roughly 23°C (74°F), making it the best time for swimming. Rainfall is moderate but often comes in heavy tropical-like downpours.

Crowd levels remain high until the final week when families prepare for school. Hotel and flight prices remain very high. This is the peak of the Atlantic hurricane season, so keep an eye on coastal warnings. Families will find the water temperatures most inviting now. A 5-to-7-day trip is recommended. Pack beach gear and quick-dry clothing.

Should you go in August? Yes, if swimming in the ocean is your primary goal.

September

September is the "local's summer." Temperatures drop to a comfortable 25°C (77°F) while the ocean remains warm. Humidity drops significantly after the first week. Rainfall is lower than in the summer months.

Crowds vanish after Labor Day (first Monday in September), making it easy to find space on the sand. Hotel prices drop by 30-40% compared to August. Flights become more affordable. Monarch butterflies migrate through Cape May during this time. Families with pre-school children will find this the most relaxing time to visit. A 4-day trip is perfect. Pack a light sweater for evenings and beachwear for the day.

Should you go in September? Yes, it is arguably the best month for a balanced New Jersey experience.

October

October features crisp air and clear skies with highs of 18°C (64°F). It is the driest month. Humidity is non-existent. The northern part of the state (Highlands/Kittatinny Mountains) sees peak fall foliage around mid-to-late October.

Crowds are moderate, concentrated at pumpkin patches and apple orchards in Chester or Long Valley. Hotel prices are reasonable, though they rise in scenic rural areas. Flights are moderately priced. Nature lovers should visit the Pine Barrens for fall colours. Families will enjoy harvest festivals. A 3-day trip is recommended. Pack a medium-weight jacket, scarves, and boots.

Should you go in October? Yes, for the foliage and comfortable hiking weather.

November

November is chilly and often windy, with highs of 12°C (54°F). The last of the leaves fall by mid-month. There is no snow yet, but the air feels sharp. Rainfall is moderate.

Crowds are low until the Thanksgiving holiday (fourth Thursday). Hotel prices are low, except near major shopping hubs like Paramus or Cherry Hill during Black Friday. Flight prices spike around the holiday. There are no major natural blooms or wildlife events. It is a good time for indoor dining and museum visits. A 2-day trip is sufficient. Pack a warm coat and windbreaker.

Should you go in November? Only if you are interested in holiday shopping or visiting family.

December

December is cold, with highs of 7°C (45°F) and lows dipping below freezing. Early snow is possible, but rain is more common. Humidity is low.

Crowds increase in towns like Cape May and Princeton due to holiday markets and light displays. Hotel prices rise for the holidays. Flights are very expensive due to Newark being a major hub. The winter solstice brings very short days. Families will enjoy the Victorian Christmas events in Cape May. A 3-day trip is standard. Pack full winter attire including thermal socks.

Should you go in December? Yes, for the festive atmosphere in historic towns.

Common mistakes

• Booking the Shore in May: While the weather is nice, the ocean is far too cold for swimming (approx. 12°C/54°F). Wait until July or August for swimming.
• Ignoring the Newark Cherry Blossoms: Many visitors go to D.C. and fight massive crowds, forgetting that Newark’s Branch Brook Park has a larger and often more accessible collection in April.
• Underestimating the Humidity: July and August humidity can make 30°C feel like 40°C. Do not plan long outdoor walking tours during the afternoon in these months.
• Visiting the Boardwalks in Winter: Most rides and many food stalls in places like Ocean City close completely from November to March.
• Commuting by car in Summer: Avoid the Garden State Parkway on Friday afternoons (southbound) or Sunday afternoons (northbound) during summer; a 2-hour drive can easily become 5 hours.
