מזג האוויר בCosta da Caparica (Caparica) בנובמבר

Lisbon forum regulars describe November as unpredictable but rarely a washout: “a nice day in the sun around 15-18°C and cold rainy days around 10-12°C,” with rain typically arriving in short bursts — “20 minutes of pouring rain then 4 hours without rain, then another 20 minutes...then 2 hours of sun.” A visit might see rain roughly 5 days across two weeks, but “always in short rain showers,” with locals simply ducking into a café to wait it out rather than treating it as a lost day. The one packing note beyond a warm layer: the calçada portuguesa paving gets genuinely slippery when wet, so proper shoes matter. November is billed as off-season, though regulars note it can still feel busy at the main sights. Our record: 17.4°C days, 13.3°C nights, 10 rain days and a 22.5kph wind — mild with real, frequent rain, matching the “short bursts, not a washout” read.

Lisbon-area forum threads describe January as running around 15C in the day and 7-10C at night on average, with real variation depending on the day - a sunny stretch can reach the high teens C, while a grey, rainy one might barely clear 10C with nights near 5C. Posters recommended warm layers and sturdy, non-slip footwear, since wet cobblestones are a genuine hazard on rainy days around the wider Lisbon coast. Costa da Caparica, just across the river, follows this same general Atlantic winter pattern rather than anything milder or wetter.

Forum posters describe a steady, pleasant Atlantic breeze here that keeps July temperatures from feeling too intense, though it also means the ocean itself stays genuinely cold - posters describe water temperatures under 20C even at the height of summer, more suited to surfing (with a wetsuit) than casual swimming. A light jacket for evenings is standard advice despite the warm days. Posters flag a practical logistics point for anyone coming from Lisbon: bus traffic to and from Costa da Caparica gets genuinely heavy in summer, so a trip that normally takes around 30 minutes can run considerably longer during peak July-August crowds.
