A three day trip to New York works best when each day stays in one part of the city. Here is the order, the closures that set it, and what to book ahead.

Written by the editorial team. The August picks come from Lonely Planet's published list; the month-by-month framing, the city advice and the coast-versus-mountain table are our own editorial judgment, not weather data.
The best destinations in Europe depend on the month you can travel: June and September suit the coast, while July and August favour altitude and the north. Summer in the south, the Alps and the Baltic behave like different seasons, so the real question is which trade-off you accept: heat, crowds or cost.
For storm and heat alerts on your own dates, check Meteoalarm, the service that gathers severe-weather warnings from European national weather services.
| Month | Heat | Crowds | What to book |
|---|---|---|---|
| June | Warm on the coast, unsettled in the mountains | Lighter than peak season | Island ferries and beach stays, once the season is running |
| July | Hottest on the Mediterranean | Heavy on the coast | Mountain huts, lifts and northern city stays |
| August | Hot in the south, peak demand everywhere | Thinner only off the standard routes | Everything, early, or a quieter alternative |
The rest of the piece goes month by month, adds a September note, then covers which cities hold up in the heat, how to choose between coast and mountain, and how to spend less.
The best places to go in June in Europe are the Greek islands, the Dalmatian coast and the Algarve, because they offer sun and swimming before peak-season demand arrives. June is the strongest month for a beach-led trip.
By country, that points to Greece, Croatia and Portugal as the best European countries to visit in June if the sea is the priority.
If you would rather have a city in June, go north. Copenhagen and Tallinn have long evenings and mild days, which makes them the best European cities to visit in June for people who plan to walk all day.
June cannot promise settled weather in the mountains, and some seasonal services are not yet running. Cable cars, huts, boat services and island ferry schedules ramp up as the month goes on, so a June timetable will not match July's.
The best places to visit in Europe in July are the ones that change altitude or latitude: the Dolomites, the Julian Alps and the Baltic and Scandinavian cities. July brings the highest heat and the biggest crowds on the Mediterranean, and moving away from the coast works better than fighting it.
The Dolomites are the obvious July trade: long, high walks instead of a hot beach. The catch is mountain weather, which can turn quickly. Start early, be off exposed ridges by midday, and read the local mountain forecast each morning. The Julian Alps offer the same high-country trade if the Dolomites are too busy.
Tallinn, Copenhagen and the Stockholm archipelago are the July options for city streets or island hopping without Mediterranean heat. Copenhagen and Tallinn are compact enough to cover on foot, and the Stockholm archipelago gives you island time by boat.
Go early and go late. Sightsee in the morning, swim at midday, and spend the hottest part of the afternoon indoors. The southern Mediterranean coasts, including the Greek islands, southern Italy and southern Spain, are the most exposed, so those need the most planning around the heat.
The best August destinations are the Albanian Riviera, Pelion in Greece, Minho in Portugal, the central Austrian spa towns, the Belgian coast and the Stockholm archipelago, because they sit off the standard summer routes, as Lonely Planet's list of where to go in August argues. August is peak demand and peak prices on the popular routes, so deciding where to visit or vacation in Europe in August is mostly a question of leaving them. Each pick below comes with a reason and a trade-off.
If August is the only option, go, but pick somewhere off the main circuit and lock in accommodation first, then ferries, mountain huts and any timed-entry tickets. If you have flexibility, June or September will serve a beach trip better. Before you plan around restaurant or shop hours in a small Italian, Spanish or French town, ask the local tourist office which places are open on your dates.
September is the coast's other window. The sea has held the summer's warmth and the peak-season rush is easing, so it is the month this guide recommends for the Dalmatian coast and the Greek islands if you can't travel in June. Ferry and hut timetables tend to wind down as the month goes on, so plan your return leg first.
The best European cities to visit in summer are the northern ones, Copenhagen, Ljubljana and Tallinn, while Rome, Athens, Seville and Madrid are hard work in July and August because of stone, traffic and little shade. For the southern four, the answer is to shift your hours: outdoors at opening time, indoors through the afternoon, out again after dark.
Cooler cities suit summer in specific ways:
Choose the Mediterranean coast in June or September, and the Dolomites, the Alps or the Baltic and Scandinavia in July and August. The table is our editorial summary of the trade-offs.
| Option | Heat | Crowds | Getting around | Best months |
|---|---|---|---|---|
| Mediterranean coast | Highest in July and August | Heaviest in July and August | Easy on the main routes, harder on islands | June and September |
| Mountains | Cooler with altitude | Busy at trailheads and huts | Needs a car or good bus links | July and August |
| Northern coast and cities | Mildest | Moderate | Straightforward by rail and ferry | July and August |
One practical note covers every region below: ferry timetables, hut openings and lift schedules are set by the operators and change by season, so read the operator's own timetable for your dates before you book anything non-refundable. If you combine a mountain stretch with a coastal one, run the connections through the itinerary validator, because ferry and bus links between regions are where these trips usually break.
June or September beats July and August for sea comfort and crowds. The trade-off is ferry frequency, which thins out at the edges of the season.
Much of the Dalmatian experience depends on catamarans and ferries between islands such as Hvar and Vis, so build an island-hopping route around the sailings rather than the other way round.
Altitude buys cooler air and costs flexibility. Huts and lifts run to their own calendars, and bad weather can end a day early, so build in a spare day.
The cheapest way to do Europe in summer is to move the trip rather than trim it: swap August on the Greek islands for June or September, or swap the Algarve for Minho or the central Austrian spa towns. Prices vary by destination and year, so compare live listings for your own dates, and see pricing if you want to know what planning help costs.
Match your priority to a month first, then take the primary pick or the alternative.
You can also combine regions, such as an Alpine week followed by a coastal week. Fortrip's AI trip planner can sketch the route in one go. For more ideas on where to go next, browse the Fortrip blog.
The Greek islands, the Dalmatian coast and the Algarve suit a beach-led June trip, and Copenhagen and Tallinn work for a city break with long evenings. Mountain weather is less settled in June, and some seasonal ferries, huts and cable cars are not yet running at full schedule.
Change altitude or latitude: the Dolomites, the Julian Alps, or the Baltic and Scandinavian cities such as Tallinn, Copenhagen and the Stockholm archipelago. The Mediterranean coast is at its hottest and busiest in July.
Pick somewhere off the standard summer routes, such as the Albanian Riviera, Pelion in Greece, Minho in Portugal, the central Austrian spa towns, the Belgian coast or the Stockholm archipelago. Book accommodation first, then ferries, mountain huts and timed-entry tickets.
The northern cities: Copenhagen, Ljubljana and Tallinn. Rome, Athens, Seville and Madrid are manageable in July and August only if you shift your day: outdoors at opening time, indoors through the afternoon, out again after dark.
