If you plan to pack the car and head to the coast today, change your plans. Seriously. Leave early, leave late, or don't leave at all.
We are looking at a perfect storm of travel chaos. The late May bank holiday weekend coincides with the start of the school half-term, triggering a massive migration of families. Throw in a sudden, intense heatwave with temperatures forecast to hit a scorching 33C in parts of southern England, and millions of drivers are targeting the exact same coastal towns at the exact same time.

The numbers are staggering. The AA estimates a massive 23.4 million car journeys will take place on Friday alone. If you get caught in the peak windows, you won't be driving. You'll be parking on the tarmac.
The Worst Traffic Blackspots and When to Avoid Them
Leisure traffic will peak between Friday afternoon and Saturday lunchtime. According to data from the RAC and traffic analysts, specific routes are virtually guaranteed to lock up. Experts at Lonely Planet have also weighed in on this matter.
If your route includes any of the following stretches, expect severe delays:
- The M4 heading west from London towards Wales.
- The M6 moving through the North West towards the coast.
- Major arteries heading toward east coast hotspots like Skegness.
- Coastal routes leading into Bournemouth, Hastings, and Torquay.
Parking data from RingGo confirms that seaside towns are massively outperforming inland locations for bank holiday bookings. Everyone wants a piece of the sand, meaning local coastal roads will choke up miles before you actually see the water.
If you must drive on Friday or Saturday, your best window is either before 7:00 AM or after 7:00 PM. Anything in between puts you right in the thick of the gridlock. Pack extra water, ensure your car’s coolant levels are topped up, and brace yourself for a long sit.
Chaos at the Ports and Border Delays
Thinking of escaping to the continent? You aren't alone. The Port of Dover is bracing for its busiest weekend of the year so far, handling more than 18,000 travellers between Friday and Sunday.
Saturday is set to be the absolute peak, with more than 8,000 travellers expected to pass through Dover. Port authorities have explicitly warned that the absolute worst time to arrive at the port is between 6:00 AM and 1:00 PM on any of these days. French border control checks are already compounding the holiday rush, so arriving without plenty of buffer time is a recipe for a missed ferry.
If you have a booking, stick strictly to your operator's arrival guidelines. Do not show up hours early thinking you will beat the queue; you will only add to the congestion outside the terminal.
Rail Strikes and Major Engineering Shutdowns
If you thought you could outsmart the traffic by taking the train, think again. The rail network is facing a dual hit from industrial action and a massive £64 million Network Rail engineering programme.
First, the strikes. Members of the Transport Salaried Staffs' Association (TSSA) are walking out on Friday and Saturday over a pay dispute. This specific action is crippling West Midlands Railway and London Northwestern Railway services. Timetables are being severely cut. Crucially, there will be no West Midlands Railway trains running after 7:00 PM on Friday, and services won't resume until after 7:00 AM on Saturday.
Even where trains are running, Network Rail is shutting down vital chunks of the infrastructure for upgrade works.
The East Coast Main Line Closure
The East Coast Main Line is completely shut down between York and Darlington from Saturday through to Monday. If you are trying to travel between London and Edinburgh, you face rail replacement buses for this leg. Expect significantly longer journey times and crowded coaches.
Great Western Main Line Disruption
Network Rail is starting a two-week upgrade on the Severn Tunnel’s power supply. Because of this, buses replace trains between Newport and Bristol Parkway starting Saturday. Only one through-train per hour will run between South Wales and London, diverted via Gloucester.
Thameslink and London Airport Routes
Thameslink services are completely cancelled through central London between Saturday and Monday due to signalling upgrades. No trains will run between Finsbury Park, St Pancras, and Blackfriars. This directly impacts travellers trying to reach Gatwick and Luton airports from the north or south of the capital. You will need to use the London Underground or alternative London terminals like King's Cross or London Bridge to connect.
How to Handle the Heatwave Delays
Sitting in a stationary car when it is 30C+ outside is not just frustrating; it is dangerous. The combination of extreme heat and gridlock means breakdown recovery services expect an unprecedented surge in calls for overheated engines and blown tyres.
Before you turn the key, do a basic five-minute check. Check your tyre pressure—hot roads increase the risk of blowouts if your tyres are under-inflated. Verify that your oil and coolant levels are correct. Most importantly, travel with far more water than you think you need. If you get stuck behind an accident on a closed motorway in 33C heat, those extra bottles of water become essential safety gear.
If you are travelling with children or pets, plan frequent stops. Map out alternative service stations along your route so you aren't forced to squeeze into the overcrowded mega-services on the main motorways.
Check live travel apps like Google Maps or Waze continuously before you set off, and look at the National Rail Journey Planner before heading to a station. If your train is cancelled or your route is red on the map, look for alternative regional routes or delay your departure by a day. Taking a bank holiday trip shouldn't mean spending your long weekend staring at the brake lights of the car in front of you.
