Baltimore weather has a reputation for being “anything but boring,” and for good reason. Because the city sits in the Mid-Atlantic, it gets real four-season variety—cold snaps and occasional ice in winter, quick warmups and showers in spring, hot and humid summers with thunderstorms, and crisp fall days that feel made for the waterfront. In addition, the nearby Chesapeake Bay and Baltimore’s harbor add subtle coastal influence: breezes that can shift temperatures, humidity that can surge in summer, and coastal-storm impacts that sometimes arrive as wind, heavy rain, or tidal flooding.
With that in mind, this guide pulls together what residents, visitors, commuters, and planners usually need: a current 7-day forecast snapshot, an evergreen climate overview using 30-year normals, a month-by-month “what it feels like” breakdown, local hazards (ice, storms, heat, flooding), plus practical packing tips. Finally, you’ll also find SEO-ready keyword clusters and FAQs you can reuse.

What this pattern suggests this week
Notably, this forecast shows a classic Baltimore winter theme: a milder, wetter push followed by a sharp cooldown. In other words, it’s “warm → wet → windy → colder,” which is a common Mid-Atlantic front sequence. As a result, your best strategy is to plan for rain, then pivot quickly to colder, breezier conditions.
Baltimore Climate Overview: What’s “Typical” vs. What’s Happening Now
Next, it helps to separate forecast from climate. A forecast tells you what’s likely over the next several days, whereas climate describes what is typical over decades. For that reason, the best baseline comes from 30-year climate normals. Specifically, NOAA’s National Centers for Environmental Information (NCEI) publishes the official U.S. normals.
Using NOAA/NCEI 1991–2020 normals for a Baltimore City station (MD Science Center), Baltimore’s climate profile looks like this:
- Annual mean temperature: ~59°F
- Annual precipitation: ~43.7 inches
- Hot days: about 43 days/year with highs ≥ 90°F
- Very hot days: about 2–3 days/year with highs ≥ 100°F
- Freezing nights: about 52 nights/year with lows ≤ 32°F
- Rain frequency: about 119 days/year with measurable precipitation (≥ 0.01″)
Taken together, this means Baltimore is neither desert-dry nor perpetually snowy. Instead, it’s “rain all year, storms in summer, fronts in spring and fall, and mixed winter precipitation” more often than not.
Meanwhile, Maryland’s broader climate context explains why the city can feel changeable. Because the state sits along common storm tracks and near the Chesapeake Bay, you get seasonal humidity, fast spring/fall transitions, and winter precipitation that can flip between rain, sleet, and freezing rain when temperatures hover near freezing.
Month-by-Month Baltimore Weather (Averages + What It Feels Like)
Now, let’s make the normals practical. Below are typical monthly highs/lows and monthly precipitation totals from NOAA/NCEI’s 1991–2020 normals for Baltimore, followed by a quick “what it feels like” interpretation.
January: Cold mornings, gray spells, and occasional icy setups
- Typical high 43.7°F, typical low 30.0°F
- Precipitation 3.07″
Overall, January is the cold anchor of the year. At the same time, Baltimore can bounce between crisp sunny days and damp, windy gray ones. Snow is possible; however, cold rain is also common in marginal patterns. Consequently, the bigger commute risk is often ice—especially early mornings—rather than deep snow.
February: Still winter, but sunlight starts to help
- Typical high 46.8°F, typical low 31.9°F
- Precipitation 2.75″
Similarly, February is winter—but it’s often brighter. Even so, sharp cold snaps can still arrive. In contrast, mild surges can temporarily push temps up, only to drop again behind the next front. Therefore, a “layer-first” approach beats betting on one outfit.
March: The first true swing season
- Typical high 55.2°F, typical low 38.7°F
- Precipitation 3.93″
In practice, March is two seasons fighting for control. For example, one week can feel springlike, while the next brings a late cold snap. Additionally, gusty fronts can make a 55°F day feel cooler than expected. As a result, pack a rain shell and expect rapid changes.
April: Mild, brighter, and more reliably springlike
- Typical high 66.8°F, typical low 48.2°F
- Precipitation 3.55″
By April, the city starts to settle into real spring. In fact, afternoon temperatures commonly land in the 60s. Still, mornings can be cool, and showers remain part of the routine. Thus, light layers and a rain option are ideal.
May: One of the best outdoor months
- Typical high 75.9°F, typical low 58.0°F
- Precipitation 3.39″
Not surprisingly, May is a sweet spot. Days are warm, nights are comfortable, and humidity is often manageable. That said, occasional thunderstorms can appear. So, keep an eye on the sky if you’re planning long outdoor stretches.
June: Summer shows up—more humidity, more storms
- Typical high 85.4°F, typical low 67.7°F
- Precipitation 3.36″
As summer arrives, warm nights become normal and thunderstorms become more frequent. Compared to July, June can feel like summer “without the maximum stickiness every day.” Consequently, it’s a popular month for visitors who want warmth without peak midsummer intensity.
July: Hot, humid, and often the wettest
- Typical high 90.1°F, typical low 72.9°F
- Precipitation 4.71″
In July, heat and humidity are the headline. Moreover, thunderstorms and downpours are common, which helps explain why July stands out as very wet in the normals.
At the same time, Baltimore averages about 43 days/year at 90°F+, and many of those cluster in midsummer.
August: Still summer, still sticky, with warm nights
- Typical high 87.3°F, typical low 71.0°F
- Precipitation 4.35″
Likewise, August stays hot, and nights often remain warm. Additionally, rain can arrive in bursts via thunderstorms or tropical moisture. Therefore, if you’re scheduling outdoor events, build a flexible plan and have a quick shelter option.
September: Transition month—often warm, sometimes wet
- Typical high 80.4°F, typical low 64.5°F
- Precipitation 4.49″
By September, evenings usually improve first. However, early September can still feel summery during the day. Meanwhile, precipitation remains relatively high in the normals, which fits the broader Mid-Atlantic pattern where late-summer systems and tropical remnants can influence the region.
October: Peak comfort—classic “sweater weather”
- Typical high 68.8°F, typical low 52.6°F
- Precipitation 3.49″
For many people, October is the most comfortable month. Days are cooler, nights are crisp, and humidity is typically lower. Even so, rain still appears occasionally. As a result, October is excellent for walking neighborhoods and the harbor.
November: Cooler, windier, and unmistakably late fall
- Typical high 57.6°F, typical low 42.6°F
- Precipitation 2.98″
As November arrives, sunsets come earlier and the city feels more wintry. In addition, cold fronts tend to bring breezy changes. So, layers matter again—especially if you’ll be outside after dark.
December: Winter returns—cold rain and occasional wintry mix
- Typical high 48.0°F, typical low 34.6°F
- Precipitation 3.66″
Finally, December can swing between mild and chilly. At times, holiday travel is affected more by cold rain, wind, and ice than by heavy snow. Therefore, monitor forecasts closely when a storm system approaches.
Baltimore Seasons: The Big Picture
Winter (Dec–Feb): Variable, often wet, sometimes icy
In general, Baltimore winters are not constant snow. Instead, they’re variable, and marginal setups are common. Importantly, freezing rain and sleet can be more disruptive than snow when surface temperatures hover near freezing. Forecast discussions often stress that small temperature shifts can change precipitation type and impacts.
Spring (Mar–May): Fast transitions driven by fronts
In spring, the “whiplash” feeling is real. Because fronts and shifting air masses pass frequently, one warm day can be followed by a chilly rain quickly.
Consequently, flexible clothing and a rain layer are more valuable than any single “perfect” outfit.
Summer (Jun–Aug): Heat + humidity + thunderstorms
During summer, warmth is reliable and humidity can be intense. For example, typical July highs are around 90°F, and warm nights are common.
Additionally, recent reporting has highlighted very muggy spells affecting cities including Baltimore, reinforcing how high dew points can amplify discomfort.
As a result, planning outdoor time for mornings and keeping a storm backup plan is smart.
Fall (Sep–Nov): Often the most comfortable overall
In contrast to summer, fall typically brings lower humidity and cooler nights. Therefore, it’s a favorite for walking, sightseeing, and outdoor dining. Even so, early fall can still be warm and occasionally wet, so check the forecast for event days.
Weather Hazards in Baltimore: What to Watch For
1) Freezing rain and wintry mix
First, icing is a standout winter hazard. Because Baltimore often sits near the temperature “battle line,” small changes can flip rain to freezing rain or sleet. Forecast office discussions frequently emphasize this uncertainty in marginal events.
Therefore, if freezing rain is mentioned anywhere in the regional forecast, assume slick sidewalks and bridges are possible.
2) Coastal storms and Nor’easters
Second, coastal storms can deliver wind, heavy rain, and water-level issues. Maryland’s climate overview notes that coastal-storm patterns can contribute to tidal or coastal flooding along the Chesapeake Bay and nearby coasts.
Consequently, shoreline and harbor-adjacent areas should pay attention to wind direction and timing.
3) Thunderstorms and flash flooding
Third, summer storms can produce intense downpours. In urban areas, rapid rainfall can overwhelm drainage quickly. As a result, localized street flooding can occur even when totals don’t seem extreme.
4) Heat waves and high dew points
Fourth, heat waves are a real concern, especially when humidity stays high. Because the city sees many 90°F+ days and warm nights, the body sometimes gets less overnight relief.
Therefore, hydration, shade, and indoor breaks become essential during peak heat.
5) Breezy cold-front transitions
Finally, strong fronts can bring sharp temperature drops and gusty winds. In other words, it can feel colder than the thermometer suggests after a front passes.
Microclimates: Why Baltimore Weather Varies Across Short Distances
Even within the city, weather can differ slightly from block to block. For example, downtown can stay warmer at night because buildings and pavement retain heat. Additionally, the harbor and Chesapeake Bay can influence wind and temperature, especially during certain setups. Moreover, small elevation and exposure differences can affect icing and wind. Maryland’s climate context also highlights how land/water patterns and prevailing winds contribute to localized differences.
What to Wear in Baltimore: A Practical Packing Guide
Winter (Dec–Feb)
To stay comfortable, use a three-layer approach. First, wear a warm base layer. Next, add a midlayer for insulation. Finally, use an outer layer that blocks wind and rain.
- Warm coat + insulating midlayer
- Gloves and hat for windy days
- Waterproof shoes/boots (cold rain and slush happen)
Additionally, if ice is possible, choose footwear with better traction.
Spring (Mar–May)
Because spring swings are common, flexible layers work best.
- Light jacket + hoodie/sweater
- Rain shell (often better than an umbrella in wind)
- Shoes that handle wet sidewalks
As a result, you can adapt quickly when mornings start chilly and afternoons warm up.
Summer (Jun–Aug)
Since humidity matters, prioritize breathable clothing.
- Lightweight outfits + comfortable walking shoes
- Sun protection (hat/sunscreen)
- Compact umbrella or light rain jacket
- Water bottle
Meanwhile, plan indoor breaks during midday heat.
Fall (Sep–Nov)
Compared with summer, fall is more comfortable, but evenings cool quickly.
- Light jacket and layers
- Closed-toe shoes for cooler nights
Therefore, bring an extra layer in late October and November.
Best Time to Visit Baltimore for Weather
If comfort is the goal, late spring and early fall usually win.
- Late April through early June: warm but often not oppressive, with cooler nights.
- Late September through October: pleasant days, crisp nights, and typically lower humidity.
On the other hand, if you want peak summer energy, June–August is lively, but you should expect humidity and thunderstorms.
Conversely, winter can be quieter and sometimes cheaper, but it demands flexibility for wet/icy disruptions.
How Often Does It Rain (and What About Snow)?
Rain
According to the normals, Baltimore averages about 119 days per year with measurable precipitation (≥ 0.01″).
However, many of those are light events, drizzle, or brief showers. In summer, precipitation often arrives as short thunderstorms rather than all-day rain.
Snow (and why totals vary)
Although snow does happen, winter precipitation type varies widely. Because temperatures often hover near freezing, and storm tracks differ, Baltimore can see rain, sleet, freezing rain, or snow depending on the setup. Forecast discussions regularly stress that precipitation type is sensitive to small thermal differences in this region.
