Last 30 days

27 of the last 31 days were warmer than the historical average for that date. Average difference: +3.8°C.

Each bar is one day, from morning low to afternoon high. Warm-colored bars are days whose mean ran above average; cool bars ran below. The dot inside the bar is the daily mean. The shaded band is the typical 10–90% range expected for that date. Average = the day's mean temperature averaged across every year of record (1940–2026) for that calendar date.

This date over the years

One dot per year — the mean temperature on this calendar date. Dots are warmer or cooler than the long-term average (dashed line); the shaded band is the typical 10–90% range, and the highlighted dot is today's forecast. Based on ERA5 reanalysis — modelled estimates, not station readings.

Weather by month

Climate overview

Amsterdam lies about two metres below sea level on the flat, water-laced delta behind the North Sea coast, ringed by water on three sides. Its climate is temperate oceanic (Köppen Cfb), strongly moderated by the sea and the prevailing westerly winds: summers are mild, with only a couple of genuinely hot days in an average year, and winters are cool, the surrounding water and city warmth keeping hard, lasting frost relatively rare. What frost there is tends to arrive on easterly winds.

Cloud and damp are the city's signature, especially from October through March, when grey, drizzly days are common; rain falls on roughly a third of all days, mostly as light showers rather than heavy downpours. Genuine extremes of heat and cold are both uncommon.

The warmest month is July, with a daily mean around 17.2°C and typical afternoon highs of 20.8°C. The coolest month is January, when daily means fall to about 2.6°C and overnight lows sit around 0.5°C.

The yearly total for Amsterdam comes to about 803 mm; monthly amounts range from 53 mm in February up to 83 mm in July.

Over the full record (since 1940), the annual mean temperature in Amsterdam has risen by 1.7°C between its first decade and its last. Where the first decade averaged 65 frost days a year, the recent one saw about 30.

Amsterdam month by month — what to expect

Typical conditions for each month, averaged across the full record (since 1940). Daylight is the time from sunrise to sunset. Record high/low are the most extreme values in the ERA5 dataset (modelled since 1940), so they can differ from official weather-station readings.

How it has changed

Year-by-year signals from 1940 to today.

Climate stripes

Annual mean shifted from 1940–1949 to 2016–2025 by +1.7°C.

Each vertical stripe is one year. Color encodes how much that year's annual mean differed from the long-term average. Average = each year's annual mean compared to the average of all years (1940–2026). cooler ← → warmer

Annual mean temperature

Long-term trend: +0.23°C per decade.

One point per year — the temperature averaged across the whole year. The dashed line is the least-squares long-term trend. Based on ERA5 reanalysis — modelled estimates, not station readings.

Seasonal warming

Dec–Feb is warming fastest: +0.37°C per decade.

Each faint line is one three-month period's average per year; the bold dashed line is its long-term trend. Different parts of the year often warm at different rates. Based on ERA5 reanalysis — modelled estimates, not station readings.

Hot days vs frost days

Days ≥ 30°C per year: 3.1 early in the record → 4.7 recently. Frost days: 63 → 32.

Thin lines are raw yearly counts; thick lines are the smoothed trend that removes year-to-year noise. The hot-day threshold is auto-picked per city so the line actually moves. Average = a centered 5-year rolling average to smooth weather noise.

Yearly hot & cold extremes

All-time high in 2019, all-time low in 1942: 37.9°C / -22.0°C.

One point per year — the single hottest and coldest day recorded that year.

Annual rainfall

~803 mm/year on average. Last decade ran +8% vs that average. Long-term trend: +26 mm per decade.

Day-by-day grid

Each tiny square is one calendar day across the full record — ~30,000 days per city. Use the mode switch above the chart: Anomaly colors each day by how far it ran from the historical average for that date (red = warmer, blue = cooler), Daily mean temp shows the absolute mean temperature for the day (useful to see seasons and heatwaves), and Precipitation shows daily rainfall (useful to spot wet/dry seasons and droughts). Average = the long-term average for that calendar date (1940–2026).
