If you wait too long to book, you will pay more. It is that simple.

In car rental, the price does not depend only on the model or the destination — it depends mainly on when you make your booking.

In this article, you will find everything you need to know: when to book to get the best price, what affects car rental prices, and the mistakes many travellers make — and that you can easily avoid.

High season and low season in Portugal: what changes in car rental prices?

Rent a car to visit Portugal on holiday

The price of car rental in Portugal varies significantly depending on the time of year. Understanding these seasonal changes is essential if you want to know when to book and avoid paying more than necessary.

High season — higher demand, higher prices

Summer, from June to September, is the period with the highest demand, which means higher prices and lower availability. Easter, Christmas and long weekends also fall into this category, as available options can sell out quickly.

Low season — more competitive prices and more choice

In winter, except during festive periods, demand drops and prices usually follow. This is the ideal time for travellers with more flexibility.

What is the best time to book a rental car and pay less?

If you need a car for a holiday during high season, it is best to book at least 4 to 6 weeks in advance. If you are travelling in low season, 1 to 2 weeks in advance is usually enough.

In addition to booking early, flexibility with dates, pick-up location and rental duration can also affect the final price.

Book in advance during high season

In high season, booking weeks or even months ahead is essential. The earlier you book, the more likely you are to find lower prices and a wider choice of vehicles. Leaving it until the last minute in July or August almost always means paying more.

Take advantage of campaigns and promotions

Many companies launch campaigns outside peak travel periods. Booking during these periods, even for a future trip, can lead to considerable savings.

Be flexible with dates and times

Travelling midweek is often cheaper than travelling at the weekend. Renting for 7 days or more can also result in much lower daily rates than renting for just 1 or 2 days.

Compare different pick-up locations

Airports are convenient, but they may include location fees. Nearby rental locations, especially those with a free shuttle service included, can often be better value without losing convenience.

Picking up your rental car in Portugal

What should you check to avoid paying more for your holiday car rental?

To avoid paying more than necessary, confirm what is included in the price, check the fuel policy, review the insurance and excess conditions, avoid unnecessary extras at the counter, and always read the contract before signing. These five simple checks can make a real difference to the total cost.

  • Confirm what is included in the price: mileage, basic insurance and roadside assistance
  • Check the fuel policy: full-to-full is usually the most transparent option
  • Review the insurance and excess conditions: what is covered and what remains your responsibility
  • Avoid unnecessary extras at the counter
  • Read the contract carefully before signing

What are the most common mistakes when booking car rental for a holiday in Portugal?

Knowing the most common mistakes is the easiest way to avoid them. Booking too late in high season, choosing only based on price without reading the conditions, ignoring additional fees such as airport fees or an extra driver, and failing to see early booking as a way to save money can all make a significant difference to the final cost.

They may seem like small details, but they can make your car rental much more expensive.

  • Booking too late in high season: fewer options and higher prices
  • Choosing only based on price without checking the conditions: the total cost can be very different
  • Ignoring additional fees: airport fees, an additional driver or out-of-hours return
  • Not reading the contract before signing: cancellation, return and excess conditions can lead to unpleasant surprises
