April is the month Amsterdam is built for. It is the driest month of the year at about 41 mm, the tulip fields peak, Keukenhof is at full colour – and on Tuesday 27 April 2027 the entire country turns orange for King’s Day, which is either the best day of your trip or the one to plan carefully around.
The weather, precisely
The statistic people find hardest to believe about Amsterdam: April is its driest month, at around 41 mm across roughly 13 days. Nowhere near dry in absolute terms, but the driest this city gets, and combined with about 14°C and long evenings it is the most reliable outdoor weather of the year.
Nights are still cold at around 5°C, and April wind can be biting. Terraces open on optimism; blankets are provided.
King’s Day, 27 April
Koningsdag celebrates the King’s birthday and is the largest single event in the Dutch calendar. In 2027 it falls on Tuesday 27 April. (The date shifts only if it lands on a Sunday, when it moves to the 26th – not the case in 2027.)
What actually happens:
- The whole city wears orange and around a million people come into the centre.
- The vrijmarkt – the free market – is the genuinely distinctive part. For one day anyone may sell anything on the street without a permit or tax. Families lay out blankets of secondhand goods across whole neighbourhoods; the Jordaan and Vondelpark, where it is a children’s market, are the classic spots. It starts early, often the evening before.
- The canals fill with boats, packed and playing music, and the whole city becomes one continuous party.
- Koningsnacht, the night before, is nearly as big.
The practical warnings matter:
- Hotel rates multiply – three to five times normal, with minimum stays – and rooms go months ahead. Book very early or stay outside the city.
- Public transport is heavily restricted. Trams and metros stop running through the centre, and Centraal Station has been closed or made exit-only at times when crowds peak. Expect to walk everywhere.
- Museums and many shops close for the day.
- It is crowded, loud and alcohol-heavy. If that is not your trip, 27 April is a good day to be in Haarlem or Utrecht instead – they celebrate too, at a manageable scale.
The tulips, honestly
Two different things get confused, and it matters:
- Keukenhof is a curated 32-hectare garden at Lisse, open from late March to mid-May, with millions of bulbs planted in designed beds plus indoor pavilions. It peaks in mid-to-late April. It is spectacular and extremely busy – go at opening or late afternoon, and buy a combination ticket with transport in advance.
- The bulb fields are commercial flower farms across the Bollenstreek between Haarlem and Leiden. These are the striped blocks of colour in the photographs. They peak mid-April to early May and are free to see – best by bicycle from Hillegom or Lisse. Never walk into a field; they are working crops and the growers mind.
Bloom timing moves by a week or two with the spring, and the fields are cut once the flower has done its job – the bulb is the product, not the bloom. Check current bloom reports before travelling specifically for them.
The Bloemencorso Bollenstreek, a flower parade of enormous floats travelling from Noordwijk to Haarlem, is usually held on a Saturday in mid-to-late April. Dates announced annually.
Prices and crowds
High season, and the highest of the year around King’s Day. The Dutch meivakantie school holiday also begins in late April, adding domestic demand. If you want April’s weather and flowers without the peak, aim for the first two weeks – the tulips are coming on, Keukenhof is open, and prices have not yet gone vertical. See what a trip to the Netherlands costs.
What to pack
Layers, a windproof waterproof and something warm for the evenings. Comfortable shoes. Something orange if you are here for King’s Day – it is not optional in spirit. Sunglasses. No umbrella.

Frequently asked
When is King’s Day in 2027?
Tuesday 27 April 2027. The date only moves if it falls on a Sunday, when it shifts to the 26th – which is not the case in 2027. Koningsnacht, the night before, is nearly as big.
What is the vrijmarkt?
The free market on King’s Day, when anyone may sell anything on the street without a permit. Families lay out secondhand goods across whole neighbourhoods; the Jordaan and the children’s market in Vondelpark are the classic spots.
Does public transport run on King’s Day?
Only partly. Trams and metros stop running through the centre, and Centraal Station has at times been closed or made exit-only when crowds peak. Plan to walk.
When do the tulips bloom in the Netherlands?
The bulb fields peak from mid-April to early May, and Keukenhof peaks mid-to-late April. Timing shifts by a week or two with the spring, so check current bloom reports if you are travelling specifically for them.
What is the difference between Keukenhof and the tulip fields?
Keukenhof is a designed garden at Lisse with millions of bulbs and indoor pavilions, open late March to mid-May and ticketed. The bulb fields are commercial flower farms across the Bollenstreek – free to see, best by bicycle, and never to be walked into.
Is April really Amsterdam’s driest month?
Yes – about 41 mm across roughly 13 days. That is the least rain of any month here, which is part of why the flower season works.
Is Amsterdam expensive in April?
Very, around King’s Day, when rates run three to five times normal with minimum stays. The first two weeks of April are much better value and still have flowers.
Should I avoid Amsterdam on King’s Day?
Only if crowds and drinking are not your thing – a million people come into the centre. Haarlem and Utrecht celebrate at a far more manageable scale and are both under half an hour away.
