October in Portugal offers a sweet spot of warm, sunny days and noticeably cooler evenings, with the Algarve and Lisbon seeing average highs of 22–24°C and sea temperatures still pleasant for swimming, though rain becomes more likely as the month progresses.
What is the weather like in Portugal during October?
October marks the transition from summer heat to autumn mildness across Portugal. The Algarve coast, including Lagos and Faro, remains the warmest region, with daytime temperatures often reaching 24°C and sea temperatures around 20°C. Lisbon and the central coast see highs of 22°C, while Porto and the north are cooler at 18–20°C with more frequent cloud and drizzle. Rainfall increases through the month, particularly in the north, but southern areas still enjoy plenty of sunshine.
Is October a good time to visit the Algarve?
Yes, October is an excellent month for the Algarve if you prefer fewer crowds and still-warm conditions. The sea is swimmable, and you can expect around 8 hours of daily sunshine. However, pack layers: evenings cool to 14–16°C, and occasional rain showers are possible, especially later in the month. For a comparison with other autumn destinations, see our Malta Weather guide.
What should I wear in Portugal in October?
Light layers are key: T-shirts or blouses for daytime, plus a jumper or light jacket for evenings. Bring a waterproof jacket or umbrella, especially if visiting the north. Comfortable walking shoes are essential for exploring cities like Lisbon.
Is the Algarve still warm in October and November?
The Algarve stays warm in October (22–24°C), but by November temperatures drop to 17–19°C with more rain. October is the better bet for beach days; November is better for hiking and cultural trips. Check our 10 Day Weather Forecast before you go.
How does October compare to September in Portugal?
September is hotter and drier, with highs of 27–29°C and minimal rain. October is cooler and wetter, but still pleasant. If you want guaranteed beach weather, choose September; for quieter sightseeing with warm days, October works well.
