Somewhere around the middle of April the city changes almost from one day to the next. American elms and horse chestnuts along the Herengracht and the Prinsengracht break into leaf within a week or so. February's dull grey light gives way to something warmer and softer. Terraces shut since October reopen, and locals, who rarely let the weather dictate anything, claim every outdoor seat the moment the sun appears. Arrive in April or May and you catch Amsterdam at its most generous.

Keukenhof and the Tulip Fields in April

Any honest spring plan starts with Keukenhof. The garden covers 32 hectares in Lisse, in the bulb-growing country roughly 35 kilometres south-west of Amsterdam. Its gates open in late March and close in mid-May. Over that short season it draws more than a million people, which puts it among the busiest attractions anywhere in the Netherlands.

Those crowds are worth tolerating, because the planting is on a scale few gardens attempt. Growers put in over seven million bulbs every autumn. Tulips lead the show, yet narcissi, hyacinths, alliums and many rare varieties fill the beds too. A different grower designs each themed section, so a walk through the grounds feels part flower show, part landscape design.

Go on a weekday, and be at the gate when it opens at 8:00. Before 10:00 the paths are far emptier, the light suits a camera better and you can actually stand back and look. Turn up at eleven on a Saturday in peak bloom and you will spend the visit shuffling behind other people.

The fields around the garden, known locally as the bollenstreek, deserve a look of their own. Long bands of single-colour tulips in pink, red, purple and yellow run flat to the horizon, a sight you will not find in quite this form elsewhere. Hiring a bike and riding between the fields on a bright April morning is a wonderful day trip from Amsterdam.

A Canal Boat in Spring

Spring suits the canals well. Water levels hold steady, fresh leaves hang over the quays and the city's 2,500-plus houseboats wake up with window boxes, parked bikes and laundry, which makes the waterways feel lived in rather than staged.

Boating options run from casual to formal. Open electric boats need no licence, so you can rent one and steer yourself around the canal ring, stopping wherever you like. Further up the scale sit private dinner boats and champagne cruises, which come with catering and a set route.

For a spring afternoon the self-drive boat is usually the better pick. Picture the Keizersgracht under its plane trees in late light, slipping beneath some of the city's 1,500 stone bridges, then tying up in a quiet side canal for a picnic. Beginners manage easily, since the canals are calm and fairly narrow and the rules are few. Floating through the middle of a capital, with 17th-century gables on both sides, surprises even repeat visitors. Our guide to seeing Amsterdam by boat covers routes and hire in more detail.

Terrace Season Opens

When the terraces come back in March and April, Amsterdam treats it almost as a public holiday. People here prefer to be outside whenever the temperature allows it. Once the thermometer reaches double figures and the clouds part, every terrace fills, often with people dressed for a warmer day than the one they are actually having.

Three parts of the city do terraces well. In the Vondelpark, pavilion cafés along the main path catch the afternoon sun and offer endless people-watching. Leidseplein and Rembrandtplein, the two big nightlife squares, have broad, busy terraces for a beer after lunch or a coffee before the evening crowd. The smaller neighbourhood spots in the Jordaan and De Pijp are slower and closer to the water, which is exactly the point of a spring afternoon.

Tall gas heaters stand on almost every terrace and stretch the outdoor season by a good four weeks at each end. Good cafés place them well, so sitting out on an April evening stays pleasant even after the temperature falls at sunset.

King's Day on 27 April

Koningsdag, or King's Day, marks the Dutch monarch's birthday, and Amsterdam stages one of the biggest one-day parties in Europe for it. On 27 April traffic disappears from the centre, decorated boats crowd the canals and roughly 800,000 people pour in from all over the country and abroad. Everyone wears orange, the colour of the House of Orange, and the mood is half festival, half block party.

The vrijmarkt, or free market, sits at the heart of the day. On King's Day anyone in the Netherlands may sell on the street without a permit, so the whole city becomes one enormous flea market. Records, vintage clothes and homemade cakes change hands on pavements, bridges and even boats. Browse with patience and you may well find something good for very little.

Plan this day well ahead. Room rates climb in the weeks around 27 April, and cars and taxis barely move through the centre. The smart move is to sleep somewhere central on 26 April, King's Eve, so the celebration comes to your door instead of making you push in from the outskirts. Reserve hotels and dinner tables for both nights weeks in advance. Our King's Day guide has more on planning the day itself.

Nobody spectates on King's Day; you join in. Picture an orange tide along the Prinsengracht, music on every bridge and boats moored five deep, and for one day few places in Europe feel happier.

April and May Weather, and What to Pack

Spring weather here deserves plain talk rather than brochure promises. April swings a lot, from about 7°C early in the month to around 15°C by its end, and showers can blow in fast and hard. May is kinder, with the warmest days reaching 18°C to 20°C, though a cold, wet week can still turn up unannounced.

Locals cope by wearing layers, keeping a light rain jacket handy and refusing to let a shower cancel a bike ride or a terrace. Copy them. Visitors who expect changeable skies and keep their outdoor plans anyway enjoy the trip far more than those betting everything on sunshine.

The reward for all that variety is the light. Golden Age landscape painters were chasing exactly these skies: racing clouds, sudden bright shafts across still canal water, dramatic evening colour. None of it is artistic licence, and spring shows it off. On a mixed April day in the Jordaan the streets can flip from brooding grey to gold and back inside an hour.

What to pack for April or May: a light waterproof shell rather than an umbrella, which the canal-side wind will fight you for, flat shoes that cope with cobblestones, thin layers to add or shed, and one smarter outfit for dinner. Take the shoe advice seriously, because the cobbles look lovely and punish heels.

Why Many Visitors Choose Spring

Several things line up in spring. The heavy crowds of July and August, when the centre can feel packed, have not arrived yet, but the city is fully awake and looking wonderful. Culture is in full flow: the Rijksmuseum, the Van Gogh Museum and the Stedelijk open new exhibitions, and concert halls and theatres run complete programmes. Terraces, hire boats and park pavilions are all open. King's Day then gives an April trip something a summer holiday cannot offer.

May keeps those advantages and adds warmth, and by the last weeks of the month the long northern evenings are building towards midsummer. Daylight lingers until about 21:30 in late May, and the canals in that slow golden dusk look as good as they will all year.

Company for a Spring Evening in Amsterdam

Many spring visitors are in town for a few nights and would like someone to share a canal walk or a terrace with. Our companions visit guests at their accommodation, and the hotel outcall page explains how a visit to your room works.
