Best Time to Book a Rental Car in Iceland: Month-by-Month Pricing

Book 3-4 Months Before Summer — Or Pay Double

Iceland's rental car market follows a brutal supply-and-demand curve. Between June and August, demand from over a million tourists collides with a limited fleet — Iceland simply does not have enough rental vehicles for peak season. The result: prices double or triple compared to winter rates, and the best vehicles (4WD SUVs) sell out entirely.

Here is the pricing pattern based on actual market data from 2024 and 2025:

Month-by-Month Pricing Guide

January-March: Cheapest

Average daily rate for a small car (Yaris/i10): 4,000-6,000 ISK. A 4WD SUV (RAV4, Tucson): 8,000-12,000 ISK. Winter is the cheapest time to rent, but you need winter driving experience and must have winter tires (mandatory by law). Availability is good — you can book a week before and still find competitive rates.

April-May: Shoulder Season

Prices begin to rise. Small car: 6,000-9,000 ISK/day. 4WD: 12,000-16,000 ISK/day. This is a good time for value — roads are improving, daylight is increasing, and you avoid the summer crush. Book 4-6 weeks ahead for the best selection.

June-August: Peak Season

This is where prices go vertical. Small car: 10,000-18,000 ISK/day. 4WD SUV: 18,000-35,000 ISK/day. Campervans: 25,000-50,000 ISK/day. And these are if you book early. Last-minute summer bookings (less than 2 weeks before) can cost 50-100% more, and 4WDs may be unavailable at any price.

The booking window: For the best summer rates, book 3-4 months in advance. For July specifically (the most popular month), 4-6 months is safer. If you want a specific vehicle type (campervan, Super Jeep), book as soon as your flights are confirmed.

September-October: Shoulder Season

Prices drop rapidly after August. Small car: 5,000-8,000 ISK/day. 4WD: 10,000-15,000 ISK/day. September is arguably the best value month for Iceland — autumn colours, northern lights starting, lower prices, and F-roads still open in early September. Book 2-4 weeks ahead.

November-December: Off-Season

Back to winter pricing. Small car: 4,000-7,000 ISK/day. 4WD: 8,000-13,000 ISK/day. Good availability. Northern lights season in full swing. December has very limited daylight (4-5 hours) but offers unique winter driving experiences.

Where to Book: Comparison Sites vs. Direct

The main comparison sites for Iceland are:

• Northbound.is: Iceland-specific comparison with good filtering options
• Guide to Iceland (guidetoiceland.is): Comprehensive comparison including reviews
• Rentalcars.com: International site with Icelandic operators

Booking directly with the rental company sometimes offers lower prices (no commission for the comparison site) and better flexibility for changes. Local companies like Blue Car Rental and Lagoon tend to have responsive customer service in English.

Cancellation Policies

Most Icelandic rental companies offer free cancellation up to 24-48 hours before pickup. This means there is no risk in booking early. If you find a better price later, cancel and rebook. Given the price volatility, this is a strategy many experienced Iceland travellers use: book early at a reasonable rate, then monitor prices and rebook if they drop.
