Winter does not change which car park is cheapest. It changes how long every stage takes, and what you find when you get back.
The booking decision is largely the same as in July. The planning around it is not, and the difference is mostly in the return leg rather than the departure.
What actually changes?
The drive takes longer — motorways carry winter traffic and are more prone to incidents and closures
Car parks are darker, so finding a space and later finding the car both take longer
Shuttle waits feel considerably longer, because standing at an exposed stop in sleet is not the same as standing in sunshine
Your car will be frozen on return, usually at night, usually when you are tired
Flights are likelier to be disrupted, which affects your parking booking rather than just your schedule
None of these are dramatic on their own. Together they are the difference between a smooth trip and an irritating one, and all of them are avoidable with ten minutes of planning.
Should I book a different car park in winter?
Consider a shorter transfer if you are returning in the evening. That is the one change genuinely worth making.
Official long stay car parks run frequent short shuttles and are well lit throughout. A distant off-airport site on a reduced evening timetable is a poorer proposition in January than in July, even at the same price.
The departure rarely needs changing. A twenty-five minute transfer at eight in the morning is much the same in any season. It is the eleven at night arrival after a delayed flight where the cheaper booking starts costing you.
Choose the car park around whichever leg is harder. In winter that is almost always the way home.
What should I leave in the car?
A scraper and de-icer. This is the single most useful thing on this page and the most commonly forgotten.
Standing in a dark car park waiting for a demister, with a perfectly good scraper sitting in your garage, is an entirely avoidable end to a holiday. It takes no space and costs nothing.
Worth adding: a torch or a charged phone, since car park lighting is designed for driving rather than for finding a key you have dropped between seats.
Does fog or snow affect parking directly?
It affects flights more than parking, but the knock-on reaches your booking. A delayed, diverted or cancelled flight means a longer stay than you paid for.
Two things protect you. Give the operator your flight number when booking, so meet and greet firms can track it automatically. And consider a flexible rate if you are travelling in a month when disruption is likelier — the premium is small against an overstay charge or a lost booking.
Scottish and northern airports see this more than southern ones. Edinburgh, Glasgow, Newcastle and Leeds Bradford all sit where weather genuinely interrupts schedules, and Leeds Bradford in particular is high enough that fog reaches it when lower airports are clear.
How much extra time should I allow?
Thirty minutes on top of your normal plan. That covers a slower drive, a longer walk in poor conditions, and a shuttle that may take longer to arrive and longer to load.
Check the route the evening before rather than trusting the satnav on the day. Overnight roadworks are more common in the quieter winter months, and a diversion at four in the morning with no traffic to follow is genuinely disorienting.
What about the car itself?
A fortnight parked outside in January is harder on a vehicle than the same fortnight in June. A few small things help:
Check tyre pressures before you travel, since they drop in the cold and a fortnight makes it worse
Leave it in gear rather than relying on the handbrake, which can freeze on in severe weather
Make sure the battery is healthy — a weak battery that starts fine daily may not after two weeks standing
Allow warm-up time before driving off, particularly if you have a long journey home
Photograph the bay number, because finding a car in a dark car park takes longer than you think
Is winter parking cheaper?
Generally yes, outside the Christmas fortnight. Late January to March is among the quietest periods of the travel year, and prices reflect that.
That is also when discount codes actually appear, because operators have space to sell. The exception is the fortnight around Christmas, which is the sharpest peak of the year and carries almost no discounting at all.
