The Netherlands is a small, flat, maritime country, so the weather is similar everywhere and rarely extreme; the calendar matters more than the map. Spring, from late March to mid-May, is the tulip window and the busiest time outside of summer. Summer is warmest but wettest and most crowded. Autumn and winter are grey and short on daylight but quiet, and the museums, canals and cafés that make Amsterdam worth visiting work perfectly well in a raincoat.
Amsterdam weather by month
Official 1991–2020 climate normals for Amsterdam Airport Schiphol, from the Royal Netherlands Meteorological Institute (KNMI):
| Month | Avg high | Avg low | Precipitation | |---|---|---|---| | January | 43°F (6°C) | 34°F (1°C) | 2.6 in | | February | 44°F (7°C) | 34°F (1°C) | 2.2 in | | March | 50°F (10°C) | 37°F (3°C) | 2.0 in | | April | 58°F (14°C) | 41°F (5°C) | 1.6 in | | May | 64°F (18°C) | 47°F (9°C) | 2.1 in | | June | 69°F (20°C) | 52°F (11°C) | 2.6 in | | July | 72°F (22°C) | 56°F (14°C) | 3.2 in | | August | 72°F (22°C) | 56°F (13°C) | 3.9 in | | September | 67°F (19°C) | 52°F (11°C) | 3.3 in | | October | 58°F (15°C) | 46°F (8°C) | 3.4 in | | November | 50°F (10°C) | 40°F (4°C) | 3.4 in | | December | 44°F (7°C) | 35°F (2°C) | 3.2 in |
Wikivoyage's summary is blunt and correct: on average it rains one day in two, year-round. April is actually the driest month in the normals and August the wettest, which surprises people planning a summer trip. Daylight is the other variable: around eight hours at Christmas, versus nearly seventeen in late June.
Tulip season and Keukenhof
The bulb fields between Leiden and Haarlem bloom from late March into early May, with tulips peaking in mid-to-late April in most years; the exact week depends on how warm March was. Keukenhof, the showcase garden in Lisse, publishes its season on its official site, and it is short: for 2027 the garden is open from Thursday 18 March through Sunday 9 May. It does not open outside those dates, so a trip in late May sees fields already cut. Book Keukenhof tickets and the Schiphol–Lisse bus in advance for April weekends, and consider a weekday morning; the park draws very large crowds at peak.
King's Day
King's Day (Koningsdag) falls on 27 April every year, moved to Saturday 26 if the 27th is a Sunday (Wikivoyage, Amsterdam). The city becomes one street party in orange, with flea markets, boat parades and closed roads; hotels fill early and prices reflect it. It is either the best or the worst day to be in Amsterdam depending on your tolerance for crowds. Because it lands in the middle of tulip season, the last week of April is the single busiest week of the spring.
Season by season
Late March–May (spring, tulip peak). Cool and comparatively dry, with the bulb fields, King's Day and Easter all inside the window. The best month for the Netherlands if flowers matter; expect spring-peak hotel rates in Amsterdam and Lisse.
June–August (summer). Warmest months at 69–72°F, long evenings, canal terraces full. Also the wettest stretch and the busiest for museums; Wikivoyage advises advance tickets or very early arrivals at the Rijksmuseum, Van Gogh Museum and Anne Frank House in summer peak.
September–October (autumn). September is often the most pleasant month: mild, quieter than summer, and the light on the canals is at its best. October turns grey and wet.
November–February (winter). Highs in the low 40s, frequent drizzle, short days. Compensations: uncrowded museums, Sinterklaas in early December, Christmas markets and the Amsterdam Light Festival, and the lowest hotel demand of the year outside the Christmas–New Year week. If a canal freeze happens, the whole country goes skating, but it is rare.
Getting there from the US
Amsterdam Schiphol (AMS) is one of Europe's best-connected airports from the US. Its destinations table lists Delta nonstops from Atlanta, Boston, Detroit, Minneapolis/St. Paul, New York–JFK, Salt Lake City, Seattle and Tampa (plus seasonal Orlando); KLM from Atlanta, Boston, Chicago–O'Hare, Houston and New York–JFK; American from Philadelphia and seasonally Dallas/Fort Worth; and JetBlue seasonally from Boston. Delta and KLM are joint-venture partners, so their flights are sold on each other's sites.
Schiphol is about 15 minutes from Amsterdam Centraal by train, and the same rail network puts Haarlem, Leiden, Utrecht and Rotterdam within an hour, so you rarely need to fly anywhere else. Flight time is about 7 hours from the East Coast and 9–10 from the West Coast with a connection or a Seattle nonstop. For today's prices see JFK to Amsterdam, Atlanta to Amsterdam, Chicago to Amsterdam and Boston to Amsterdam.
When fares tend to be lowest
Transatlantic demand to Amsterdam peaks in June–August and again over Christmas and New Year, with a secondary bump for tulip season and King's Day in April. The slow months are mid-January to early March and November, and that is also when airlines have the most unsold seats. Because Schiphol is a hub, late spring and autumn fares can also be pulled down by competition among the many carriers routing through it.
That is a demand-calendar argument, not a price forecast. Fares on any specific route depend on capacity and competition, so pick your window, check the route page for what it is actually pricing today, and set a price alert with a target you would be happy to pay. Wildly checks the route daily and emails you when the fare drops.
Entry requirements for US citizens
The Netherlands is in the Schengen Area, and US passport holders can visit visa-free for up to 90 days in any 180-day period (Wikivoyage, "Get in"). Your passport should be valid for at least three months beyond your departure from Schengen. The EU has been phasing in new border systems for visa-exempt visitors, so check the current requirements with the Dutch embassy or the EU's official travel site before you fly.
