9月のラゴスについての旅行者の声
Lagos-forum threads on September weather describe warm, lovely days undercut by cool, windy evenings - the far-western Algarve is called always windy, which makes the coast feel cooler than the daytime number suggests, and posters recommend a jacket, a wrap and an umbrella even on a sunny-looking day. Precipitation is called unusual through the early part of the month, with the back half more unsettled. The trade-off is worth it by most accounts: good weather, a fair number of tourists but not overwhelming, everything still open with nightlife running. The record: 26.8C days feeling like 27C, 18.1C nights, just 11mm across two days, a 17.6C sea still cool for swimming, and 11.1 hours of sun.

Regulars are specific the dry season is well established here by the end of this month, with real rain typically not returning until the end of September, though an earlier shower or two in the first half remains a genuine possibility. Our row backs that mild, genuinely dry read, 23.4C over 15.1C nights feeling 14C, with rain light at 21.5mm across 3.7 days and a real 22.1 kph wind. Regulars are consistent the wind here makes conditions feel cooler than the number alone suggests, especially after dark, a jacket worth having even after a warm, sunny day. Mosquito repellent is a genuinely practical addition to the packing list alongside the usual sun protection. The sea sits at 17.2C. The record: 12.7 hours of sun, humidity 68 percent and AQI 46.
Lagos-forum threads on November weather describe a genuinely mixed month: some days cool and cloudy or wet, others warm enough for a light jacket to come off entirely, with the southern Algarve running noticeably drier and milder than Lisbon or the country's north during the same stretch. What sets Lagos apart from the Algarve's smaller resort towns, per regulars, is that it keeps functioning through the winter - a real year-round local population means cafes and shops stay open, and accommodation prices sit at their lowest. The catch some posters flag: on a genuinely bad-weather day, the town can turn notably windy and quiet after dark. Regulars still call most November days mild enough for a coastal walk or sightseeing. The record: 19.2C days feeling like 18C, 13.2C nights, 47mm across 8.1 days, a 17.1C sea, 78 percent humidity and 8.4 hours of sun.
June in Lagos is dry and warm on land and cold in the water, and the forum's explanation is one sentence: this is the Atlantic, not the Mediterranean. The regional sea runs about 18 to 20C in June, and Lagos, Sagres and the west-facing coast sit at the cold end of that, below 20, because water comes up from the Atlantic depths regardless of what the Gulf Stream is doing 30km offshore. Our row says 18.4C. The sea can also be rough here in summer. The air is the opposite story - normally in the 30s, occasionally to 40 in the region - though our row's 25.9C for Lagos itself is tempered by a 23 kph wind. The record: 17.3C nights, 2 precipitation days carrying 6.1mm and 13.1 hours of sun.
August in Lagos is reliably clear and anything from the high 20s to the high 30s C, with a breeze that regulars credit for making it bearable - though some afternoons it gets strong enough to blow you off the beach, which happens more often further west than here. The sea is the Atlantic and swings with the current: anywhere from about 19C to 24C, cooler here than in the eastern Algarve around Tavira. The crowd advice is unanimous and blunt - avoid August if you can, and take September instead for the same weather with far fewer people. The record: 29.3C days, 19.1C nights, no precipitation days at all, 12.4 hours of sun, a 16.8C sea and a 23 kph wind.

Dolphins offshore
4月1日〜10月31日 · 例年ホエールシーズンCommon and bottlenose dolphins are close in from spring to autumn and the same small boats run the grotto trips at Ponta da Piedade. Morning sailings get the flat water.
- 要注意
Wildfire season inland
6月15日〜9月30日 · 例年煙害シーズンMonchique burns badly every few summers and the smoke reaches the coast on a north wind. The beaches are not at risk; the roads and the walking country behind them are. 出典 ↗

Sea warm enough to swim
7月1日〜10月5日 · 例年The western Algarve sits closer to the Atlantic than the eastern half and runs a few degrees behind it all summer. Meia Praia is the warm side of town; the west-facing beaches are not.
- 季節
West coast swell season
9月15日〜4月30日サーフシーズンWinter lows put swell on the exposed west coast around Sagres and Arrifana, forty minutes away, while the south-facing town beaches stay flat. That split is why people base here.
