Winter Rentals in Cascais: Spend the Winter on the Portuguese Coast

What is the weather like in Cascais in winter?

Mild, with a wet autumn and early winter. IPMA publishes 1991 to 2020 climate normals for its Lisbon station (Instituto Geofísico), the nearest published guide. The mean temperature is 12.4 °C in December, 11.8 °C in January and 12.8 °C in February. The mean daily maximum is 15.4 °C in December, 15.1 °C in January and 16.4 °C in February. Mean minimums are 9.4, 8.6 and 9.1 °C.

November averages 15.0 °C and March 14.9 °C. Rain is heaviest in November at 133.9 mm, then December at 108.5 mm and January at 103.8 mm. February has 77.8 mm and March 68.7 mm. January and December each average 10.0 days with 1 mm of rain or more, and February 7.9. The station records no days below 0 °C in any month of the year. It sits in Lisbon, so Cascais will differ a little. Ask the team how your home is heated.

Read the November to March rows. The average nightly rate across the 34 homes was €150 in November, €174 in December, €173 in January, €116 in February and €130 in March. Occupancy ranged between 35% in December and 48% in March, against 73% in July. That means homes were free more often, which gives winter guests more to choose from.

How long do winter guests stay, and when do they arrive?

The typical winter stay lasts six weeks, and most begin after the new year. The median winter stay of 28 nights or more lasted 42 nights. Of the 34 winter arrivals, 26 came in January or February. All winter bookings, including short ones, averaged 9.8 nights, against 6.2 nights in summer (June to September).

The data shows who stays long and not why, so we will not guess at motives. What it does show is that a long winter stay in Cascais is not unusual in our homes. If you want a stay of a month or more, our monthly rentals page has the price tables for the whole year, and the mid-term rentals page explains how these stays work.

When should you book a winter stay?

Book as early as your plans allow, since 26 of the 34 winter long stays in our records arrived in January or February. Across 990 bookings that started in the 12 months to 31 October 2026, the median guest booked 27 days before arrival, 38% booked 14 days or less ahead and 19% booked more than 90 days ahead. Those figures cover all stays and not only winter ones.

Availability changes daily and depends on the dates. Check the booking page, or write to the team for a quote on your dates and for what each home includes.

How long can visitors from outside the EU stay?

The European Commission says that when you visit the Schengen Area you are usually allowed to stay for a maximum of 90 days within any 180-day period. Its short-stay calculator page tells you to count back 180 days from each day of your stay and make sure the total does not exceed 90. The same page says that holders of an EU residence permit or a long-stay visa are not subject to the 90/180-day rule, and that holders of a short-stay visa should check the authorised period printed on the visa sticker.

A median winter stay of 42 nights fits inside 90 days. A whole winter from November to March is about 150 days, which does not. If you are not an EU citizen, use the Commission's short-stay calculator before you book and check your own situation with a Portuguese consulate or the official immigration authorities. We cannot give immigration advice.

Can you live in Cascais in winter without a car?

You can use the CP Cascais line to reach Lisbon.
