The heat is over: Lisbon to reach 19 °C on Thursday, inland north as low as −2 °C at night. Rain from Friday
The heat that lasted in Portugal until the end of October is over. Since 2 November, cold air from deep within Europe has been moving over the country, and temperatures will keep falling until Thursday 5 November, according to the weather institute IPMA. As recently as 30 October, Coruche recorded 30.2 °C, and at many IPMA weather stations the heat of those days qualified as a heatwave (Notícias ao Minuto).
From 3 November, daytime temperatures across almost the whole country are 17–22 °C. The Alentejo, the inland Algarve and the Tejo valley are 1–3 degrees warmer, while north-eastern Trás-os-Montes and Beira Alta see 12–16 °C. Nights are 5–9 °C, slightly warmer on the coast south of Peniche, and between −2 and 4 °C inland in the north and centre of the country, where there may be frost in places.
IPMA's forecast for Thursday 5 November gives Lisbon about 9 °C at night and 19 °C by day, Porto 6 °C and 16 °C, and Évora 5 °C and 20 °C. In Bragança temperatures will hover around freezing on Wednesday and Friday nights, and dip slightly below on Thursday night (IPMA forecast).
After the cold, the rain returns. On Friday 6 November there is an 80% chance of rain in Lisbon and 78% in Porto, rising to 90% in Porto on Saturday. Forecasts for each city are on our weather page.
