Is January Right for You?
Weigh the advantages and considerations before booking
- + Empty beaches stretch for kilometers—you'll have Praia do Guincho's 2 km (1.2 miles) of sand mostly to yourself for sunrise walks.
- + Hotel rates drop 30-40% from summer peaks—the sea-view rooms at historic properties become surprisingly accessible.
- + Storm watching season delivers dramatic Atlantic waves crashing against Boca do Inferno's cliffs—a photographer's dream.
- + Local life emerges—cafes along Rua Frederico Arouca fill with residents instead of tourists, and you'll hear Portuguese instead of English.
- − Atlantic winds whip through town at 25-35 km/h (15-22 mph)—that seafront promenade stroll requires a proper jacket, not just a sweater.
- − Ocean temperatures hover around 15°C (59°F)—swimming without a wetsuit is painfully cold for most people.
- − Rain arrives in sudden horizontal sheets that soak you in minutes—outdoor dining becomes a gamble even under awnings.

Best Activities in January
Top things to do during your visit
January's empty bike paths connect Cascais to Guincho through pine forests where you can hear Atlantic waves crash below. The 9 km (5.6 mile) ride from town to Guincho Beach feels almost private—you'll pass more fishermen than cyclists. Stop at Boca do Inferno where winter storms create explosions of spray that summer visitors never witness.
January's mist rolling through Sintra's hills creates the mystical atmosphere that attracted Portuguese royalty. Pena Palace emerges from fog like something from a fairy tale, and you'll walk its ramparts without the summer tour groups. The 20-minute train ride from Cascais connects through Portais station—locals know this route avoids Lisbon transfers.
Winter swells deliver Cascais's best surfing conditions—consistent 1-2 meter waves at Carcavelos Beach with water warm enough for 4/3 wetsuits. January's empty lineup means more waves per session, and local surf schools offer smaller group sizes. The town's surf culture reveals itself in winter when only committed locals paddle out.
January drives locals into traditional tascas where fishermen still lunch on caldeirada (fish stew) at tables older than most tourists. The narrow lanes around Largo de Camões hide family-run spots serving grilled sardines with cornbread—the kind of place where menus don't exist and grandmothers run the kitchen. Winter is when you taste authentic Cascais, not tourist versions.
January Events & Festivals
What's happening during your visit
Cascais honors its patron saint with processions through the old town where locals carry the saint's image past 16th-century churches. The religious ceremony at Igreja de São Sebastião fills with incense and chanting that echoes off baroque walls—a glimpse into Portuguese traditions unchanged for centuries.
Guincho Beach hosts Portugal's biggest winter surf competition where Atlantic storms deliver 3-meter waves that attract Europe's best surfers. The cliff-top viewing areas let you watch surfers tackle massive sets while staying warm with coffee from beachside stalls—it's surfing's rawest form.
