Winter may be coming to an end, but Brooklyn’s March forecast is far from predictable. As the city transitions into spring, residents can expect a wild mix of freezing mornings, unseasonable warmth, and heavy rainstorms that could disrupt travel and daily activities. Meteorologists warn that this month will be a battle between winter’s final grip and spring’s early arrival, leading to drastic temperature swings, icy commutes, and potential flooding as rain replaces snow in the coming weeks.
Temperature Swings: From Winter Chill to Spring Teasers
Brooklyn is used to unpredictable March weather, but this year is shaping up to be even more erratic than usual.
- Early March: A strong cold front will dominate the first week, bringing overnight lows in the 20s°F (-6°C to -1°C). Mornings will be frigid and breezy, making it feel much colder than the actual temperature.
- Mid-March: A sudden warm-up will bring highs into the upper 50s°F (14-16°C), tricking some into thinking spring has arrived. However, don’t be fooled—cold air could rush back in, causing dramatic drops into the 30s°F (1-4°C) overnight.
- Late March: The transition to spring will slowly take hold, but not without a few final cold snaps, especially in the evenings.
Brooklynites will need to layer up as they head out each day, since temperatures could shift by 20 degrees in just a few hours.
Heavy Rain and a Risk of Flooding
While snowfall is still possible in early March, the biggest weather threat this month will be rain—and lots of it. Meteorologists predict above-average precipitation, with multiple rainstorms bringing heavy downpours and gusty winds. The combination of melting snow and frequent rain showers could lead to flooding in low-lying areas, especially near Coney Island, Gowanus, and parts of Williamsburg.
Expect:
- Slow and slick commutes as rain creates ponding on roads and reduces visibility.
- Potential subway delays, as water levels rise in flood-prone stations.
- Messy conditions for outdoor activities, with soggy parks and muddy sidewalks.
For those who rely on public transportation, carrying an umbrella and waterproof gear will be essential throughout the month.
Why is Brooklyn’s Weather So Unpredictable?
The chaotic mix of cold snaps, sudden warmth, and endless rain is due to La Niña, a climate pattern that disrupts normal weather cycles. With cooler-than-average Pacific Ocean temperatures, La Niña is sending unsteady air masses across the Northeast, causing erratic temperature shifts and stormy weather. This is why Brooklyn could see 60°F (16°C) one day, followed by a freezing night and a rainstorm the next.
How to Stay Ahead of Brooklyn’s Unstable March Weather
Since the forecast will be changing quickly, Brooklyn residents should take extra precautions to avoid getting caught in unexpected conditions:
- Layer Up: Mornings will be cold, afternoons mild, and nights could swing either way—so dress in removable layers to stay comfortable.
- Prepare for Rain: Waterproof shoes, coats, and umbrellas will be a necessity as heavy rainstorms move through the city.
- Watch for Flooding: If you live in a flood-prone area, check storm drains and avoid walking or driving through deep water after heavy rains.
- Stay Updated: The weather could change quickly, so check forecasts daily to avoid surprises before heading out.
Will Spring Finally Arrive?
While March will be a mess of unpredictable conditions, meteorologists predict that April will bring more stable spring weather. The coldest mornings will fade away, and Brooklyn should finally see more consistent warmth and sunshine. Until then, expect the unexpected—Brooklyn’s March weather will be anything but ordinary.
