Best For:
- Walkers in mild temps

Why Visit in March
March offers manageable 50-63F temperatures ideal for hiking coastal paths without summer heat. Rainfall totals 101mm but falls in short bursts, leaving crisp air and vibrant green landscapes from winter recovery. Tourist numbers remain low post-winter, securing easy access to sites and parking. Emerging spring flowers dot parks and cliffs, while sea breezes stay refreshing. Fewer visitors mean shorter waits at eateries, and daylight stretches to 12 hours by month's end, extending usable exploration time. Shoulder season pricing on lodging beats peak rates, making extended stays practical.
Drawbacks in March
101mm rain often arrives in frequent showers, interrupting plans and slicking paths. Evenings dip toward 50F, demanding layers for wind-exposed coasts. Overcast skies mute dramatic lighting at viewpoints, and persistent dampness permeates indoor spaces. Some trails close briefly after heavy downpours, limiting access. Blooming pollen may bother sensitive visitors, while cooler seas deter swimming. Weekends see slight upticks from Lisbon day-trippers, crowding narrow streets marginally.
Best Weeks in March
- Early: March 1-10: 52-60F. Lowest crowds, steady mild conditions.
- Mid: March 11-20: 51-63F. Peak warmth emerges, very low crowds.
- Late: March 21-31: 50-63F. Warmest averages, minimal crowds before spring rush.
Recommendation:
Target mid to late March (11-31) for 51-63F highs, balancing warmth and low crowds. Early avoids initial rains but cooler; all periods suit with rain gear, prioritizing sun breaks for coastal views.

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
Cool mornings call for light, moisture-wicking base layers to handle humidity and chill. High-waisted leggings provide supportive coverage under tunics for dress codes on rainy days.
Key features: Moisture-wicking materials, High-waisted for modesty, Seamless under layers
Recommended:
- High-waisted travel leggings - moisture-wicking for humid air
- Light merino tank top - breathable against skin
- Long-sleeve thermal tee - quick-dry for showers
Avoid: Skip thick cotton bases; they hold dampness from frequent rain and feel heavy by afternoon.
Mid Layers
Daily swings from cool starts to mild afternoons need versatile mid layers. Opt for cardigans or wraps that layer easily over bases for cathedrals or casual strolls.
Key features: Lightweight and packable, Button-front for adjustability, Drape styles for dress codes
Recommended:
- Oversized knit cardigan - adjustable warmth
- Light fleece pullover - breathable insulation
- Pashmina wrap - multi-use for swings
Avoid: Don't overload with bulky sweaters; they're impractical for mild afternoons and pack poorly.
Outerwear
Frequent showers demand a waterproof outer layer that's packable for mild days. Pair with mid layers for protection on cobblestone streets without overheating.
Key features: Waterproof and breathable, Packable into pouch, Hooded for rain coverage
Recommended:
- Packable rain jacket - waterproof shell
- Lightweight windbreaker - blocks chill breezes
- Water-resistant trench - dressy over outfits
Avoid: Avoid non-waterproof jackets; they'll soak through quickly during expected downpours.
Footwear
I'd pack two to three pairs: supportive walkers for cobblestones, versatile dressy flats, and water-resistant option for showers. High arches need cushioning all day.
Key features: Water-resistant uppers, Cushioned arch support, Non-slip soles
Recommended:
- Waterproof walking sneakers - grippy on wet stones
- Ankle boots - versatile for dress codes
- Leather loafers - polished for evenings
Avoid: Never rely on open sandals alone; cool damp mornings make toes miserable on uneven paths.
Bottoms
High-waisted leggings pair with tunics for modesty at museums or churches. Choose quick-dry fabrics suited to rain and humidity for active days out.
Key features: Stretch with support, Pocketed for essentials, Quick-dry materials
Recommended:
- High-waisted leggings - supportive under dresses
- Travel pants - wrinkle-resistant fit
- Midi skirt - flows over cobblestones
Avoid: Steer clear of loose jeans; they cling when wet and hinder movement on hilly walks.
Accessories
Scarves solve temperature swings and dress codes—drape for coverage or warmth. Add sun protection for moderate UV during brighter afternoons.
Key features: Multi-functional uses, Compact and lightweight, UV-protective fabrics
Recommended:
- Silk scarf - layers for modesty
- Wide-brim hat - shields from sun
- Compact sunscreen - daily reapply
Avoid: Don't forget a hat; exposed skin burns fast even under cloudy skies with showers.
Bags & Luggage
My tip: crossbody for hands-free security on busy streets, plus packable daypack for outings. Keep it light to navigate cobblestones easily.
Key features: Anti-theft zippers, Water-resistant nylon, Adjustable straps
Recommended:
- Crossbody sling bag - secure for essentials
- Packable daypack - folds small
- Rolling carry-on - smooth wheels
Avoid: Overpack large totes; they're cumbersome in rain and snag on narrow paths.
