Is April Good for Aarau?
Yes, Good
Mild 38-63F temps with 83mm rain yield spring showers and fresh greenery. Low crowds suit relaxed visits; occasional sun highlights landscapes.
Best For:
- Walkers in mild temps
- Crowd-avoiders
- Early-season explorers
Why Visit in April
April delivers manageable 38-63F temperatures, thawing winter for budding trees and vibrant greenery without summer heat. Rainfall totals 83mm but often in short bursts, leaving crisp air ideal for outdoor activity. Tourist numbers remain low post-winter, securing better rates on stays and easier navigation. Spring energy emerges with longer days, suiting extended walks. Local events kick off, adding distinct flavor. Fewer visitors mean worthwhile photo ops in natural light. Practical for those seeking scenery refresh before peak season.
Drawbacks in April
Frequent showers from 83mm rain can interrupt plans, with slick paths after downpours. Early mornings and evenings dip to 38F, requiring layers against chill. Overcast skies mute colors at times. Urban areas may feel damp, and rural spots muddy. Wind occasionally picks up, making viewpoints brisk. Limited indoor alternatives if rain persists all day.
Best Weeks in April
- Early: April 1-10: 38-60F. Lowest crowds, crisp starts.
- Mid: April 11-20: 39-62F. Balanced warmth, steady low crowds.
- Late: April 21-30: 40-63F. Warmest, still minimal crowds.
Recommendation:
Target late April 21-30 for peak 40-63F temps and drier trends, minimizing chill while crowds stay low. Mid-period works if seeking value; avoid early if rain-sensitive, as it eases later. All windows offer quiet exploration.

6 Mistakes to Avoid
Packing Non-Packable or Heavy Outerwear
Many travelers include structured blazers, leather jackets, or thick denim jackets that rarely get used.This leads to: Wasted luggage space and weight, Overheating once temperatures rise, No room for souvenirs
Solution: Choose ultralight, truly packable layers that compress to nothing.
Pack instead: Women's packable down or synthetic puffer, Ultra-lightweight nylon trench, Thin merino or cashmere cardigan
Choosing the Wrong Footwear for Cobblestones
Bringing only one or two pairs, or selecting shoes that look good but lack real support.This leads to: Blisters after 10-15 km days, Ankle rolls on uneven surfaces, Ruined shoes from sudden showers
Solution: Experienced travelers select 2-3 versatile pairs that cover every situation.
Pack instead: Cute white sneakers with arch support, Water-resistant low ankle boots, Foldable ballet flats with cushioning
Overlooking Church and Venue Dress Codes
Wearing sleeveless tops or cropped leggings without easy cover-ups.This leads to: Denied entry at cathedrals and major sites, Expensive last-minute scarf purchases, Disrupted plans
Solution: Pack one multi-use cover piece that works with every outfit.
Pack instead: Large lightweight scarf (shoulder + knee cover, Long tunic that layers over leggings, Packable kimono or wrap
Underestimating Rain Protection
Relying on a tiny travel umbrella instead of proper clothing.This leads to: Soaked leggings and ruined makeup, Cold wet feet for hours, Forced to skip outdoor sights
Solution: Add stylish, truly water-resistant pieces that still look polished.
Pack instead: Women's packable rain shell or trench, Quick-dry high-waisted leggings, Water-resistant cute walking shoes
Overpacking Accessories and Bags
Bringing multiple handbags, statement necklaces, and heavy earrings.This leads to: Security hold-ups, Neck and shoulder pain, Higher pickpocket target
Solution: One bag + two scarves + minimal jewelry cover every look.
Pack instead: Small crossbody bag with RFID, One large scarf (doubles as cover-up), Simple stud earrings
Wearing Brand-New Items Without Testing
Buying new leggings, bras, or shoes days before departure.This leads to: Chafing from stiff seams, Blisters on day one, Wardrobe malfunctions mid-trip
Solution: Every new item must survive several 10 km+ test walks at home.
Pack instead: Pre-worn travel leggings, Broken-in supportive sneakers, Already-tested packable jacket
What to Pack: Category by Category
A detailed breakdown of every clothing and gear category you need, with specific recommendations tailored to the exact weather and activities you'll encounter.
Base Layers & Thermals
Cold mornings call for insulating thermals that handle humidity and layer easily under outfits. High-waisted leggings provide support for long walks on cobblestone streets while wicking sweat effectively.
Key features: Merino for odor control, Moisture-wicking fabrics required, Seamless designs prevent rubbing
Recommended:
- High-waisted thermal leggings - moisture-wicking with secure pockets
- Merino long-sleeve top - breathable insulation
- Lightweight thermal tank - quick-dry base
Avoid: Skip cotton undershirts—they trap moisture from showers and cling uncomfortably during mild afternoons.
Mid Layers
Daily swings from chilly starts to milder times mean versatile pieces like cardigans add or shed warmth. My tip: opt for drapey styles that double for cathedral visits with a scarf.
Key features: Layerable for temp changes, Lightweight packable fleeces, Wraps for quick coverage
Recommended:
- Oversized cardigan - versatile over dresses
- Light fleece pullover - wind-resistant warmth
- Pashmina wrap - modesty and insulation
Avoid: Avoid bulky sweaters—they overheat in afternoons and pack poorly for active days.
Outerwear
Packable rain shells guard against occasional showers without bulk. Mid-weight jackets handle cool mornings yet breathe in humid air for museum strolls or street wandering.
Key features: Waterproof breathable shells, Hooded for rain protection, Packable into own pocket
Recommended:
- Packable rain shell - seam-sealed waterproofing
- Lightweight quilted jacket - windproof layer
- Trench-style coat - dressy for evenings
Avoid: Don't bring heavy wool coats—too much for mild afternoons and hard to stow.
Footwear
Supportive walkers tackle cobblestones; add water resistance for showers. Pair with dressy flats for dinners, optional sandals if afternoons warm up nicely.
Key features: Cushioned arch support, Water-resistant uppers, Grip soles for stones
Recommended:
- Ankle walking boots - waterproof and stable
- Versatile leather loafers - dressy yet walkable
- Packable sandals - for milder days
Avoid: Steer clear of flimsy sneakers—they slip on wet stones and lack ankle stability.
Bottoms
High-waisted leggings pair with tunics for modesty at cathedrals while stretching for hikes. Mix in chinos for varied looks that layer under rain gear easily.
Key features: Stretch for mobility, Quick-dry materials, High-waisted for coverage
Recommended:
- High-waisted travel leggings - pocketed and supportive
- Ankle-length chinos - wrinkle-resistant
- Midi skirt - flowy over thermals
Avoid: Forget skinny jeans—they restrict movement on uneven paths and retain dampness.
Accessories
Scarves solve dress codes and chilly swings; pack sun hat for moderate UV during walks. I'd toss in gloves for mornings—practical without fuss.
Key features: Multi-use scarves, UV-protective hats, Compact sun essentials
Recommended:
- Silk scarf - layers for modesty
- Wide-brim hat - sun and rain shield
- Light gloves - fingerless for dexterity
Avoid: Overlook reusable sunscreen—it beats greasy lotions that melt in a daypack.
Bags & Luggage
Crossbody bags keep hands free on crowded streets; packable daypack hauls layers for swings. Depends on rain luck, but security trumps style here.
Key features: RFID-blocking pockets, Water-resistant fabrics, Lightweight expandable
Recommended:
- Crossbody sling - anti-theft zipper
- Packable daypack - holds rain shell
- Rolling carry-on - cobblestone-friendly wheels
Avoid: Ditch large totes—they snag on streets and invite pickpockets in busy spots.
