9月的波尔蒂芒旅人笔记
来自附近拉古什的笔记（相距 13 公里）
波尔蒂芒还没有自己在9月的笔记——下面这些是关于拉古什的，离得够近，季节相同。
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.
波尔蒂芒的其他月份
Portimão's forum describes December as changeable but mild by northern European standards - typical days around 17C, occasionally reaching 20C, dropping to 8-10C overnight. Rain shows up regularly but posters were clear it's not an all-day, every-day thing, and the prevailing northerly wind is the bigger factor in how cold a day actually feels. For a rainy day, several people pointed to Portimão's indoor shopping malls, while clear days are good for trips inland to Silves, Monchique or the Foia mountain. Most cafes and restaurants stay open through the off-season.
Forum posters describe June temperatures building through the month - typically 24-25C early on, climbing to 27-30C by the end - with genuinely warm, sunny days the norm and rain called unusual. One visitor's mid-June report described perfect, hot and sunny weather with a pleasant sea breeze and no cloud cover. Posters do note a real evening chill factor: a sudden drop from 27C daytime down to around 20C once the sun sets and a breeze picks up, so a light layer for the evening is standard advice even during an otherwise hot stretch. The clear appeal of June specifically: pleasant, reliably warm weather without the full crowds and peak prices of July-August.

- 季节
Sea warm enough
6月25日 – 10月5日 · 通常This is the Atlantic rather than the Mediterranean and upwelling keeps it a couple of degrees cooler than the eastern Algarve. The sheltered coves west towards Lagos warm faster than the open Praia da Rocha.
- 风险
Serra de Monchique fire season
7月1日 – 9月30日烟霾季The eucalyptus hills behind the coast burn most summers and a bad one puts smoke over the whole bay and closes the road up to Monchique. The coast itself is rarely at risk. 来源 ↗
