อากาศCosta da Caparica (Caparica) เดือนมิถุนายน

The sardinhas run all June - bunting across the streets, trestle tables and charcoal braziers set out by restaurants and households - but regulars are clear the month has a single night. The 12th, with the parade and the Alfama crush, is a bigger occasion here than New Year and runs until morning, with parties across Santos, Graca and Bica as well. Around it the weather is the easy part: hot without July's heat, 25.6C by day and 16.9C at night, 9.7mm of rain across 3.1 days, and 12.9 hours of sun. The Atlantic keeps the sea at 19.8C and the breeze at 24.4 kph. The record: humidity 73 percent and AQI 42.

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.
