Is September Right for You?

Advantages

Perfect walking weather with comfortable 18-27°C (64-81°F) temperatures - ideal for exploring neighborhoods like Federal Hill and Fell's Point without summer heat exhaustion

Considerations

Hurricane season can bring unexpected weather changes and occasional coastal flooding to waterfront areas like Canton and Harbor East

Daylight decreases significantly - sunset moves from 7:30pm to 6:45pm during the month, limiting evening outdoor photography

Essential Tips

What to Pack

Light layers for 9°C (16°F) daily temperature swings - mornings can be cool at 18°C (64°F) while afternoons reach 27°C (81°F)

Waterproof walking shoes for occasional rain (8 rainy days average) and cobblestone streets in historic areas

Light rain jacket or compact umbrella - September showers typically last 30-45 minutes but can be sudden

SPF 30+ sunscreen for UV index 6 - still significant sun exposure during harbor and outdoor activities

Comfortable walking shoes with good support - exploring neighborhoods involves 3-5 km (2-3 miles) daily walking on varied surfaces

Light sweater or cardigan for evening harbor breezes and indoor air conditioning in restaurants

Portable phone charger for navigation and photography during full-day neighborhood exploration

Small backpack or crossbody bag for carrying water and layers while walking between attractions

Cash for parking meters and small vendors - many historic area businesses still prefer cash payments

Insider Knowledge

Ravens home games cause downtown traffic nightmares - avoid driving near M&T Bank Stadium on game days, use Light Rail instead which runs directly to stadium

Best crab houses are in neighborhoods like Canton and Locust Point, not touristy Inner Harbor - locals drive 15-20 minutes for significantly better crabs at 30% lower prices

Free parking exists in Federal Hill residential streets after 6pm and weekends, saving $15-25 daily compared to Inner Harbor lots

Many museum and attraction discounts available through Baltimore CityPASS ($89 vs $150+ individual admission) - worthwhile if visiting 3+ major sites

Avoid These Mistakes

Underestimating walking distances in historic areas - GPS shows shorter times because it calculates straight lines, but cobblestone streets and waterfront detours add 20-30% to walking time

Booking Inner Harbor restaurants without checking Ravens schedule - game days mean 2-3 hour waits and inflated prices at nearby establishments

Wearing flip-flops or sandals for sightseeing - cobblestone streets in Fell's Point and Federal Hill require closed-toe shoes with ankle support
