How it has changed

Year-by-year signals from 1940 to today.

Climate stripes

Annual mean shifted from 1940–1949 to 2016–2025 by +1.5°C.

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

Hot days vs frost days

Days ≥ 30°C per year: 154.4 early in the record → 296.1 recently. Frost days: 0 → 0.

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. Normal = a centered 5-year rolling average to smooth weather noise.

Yearly hot & cold extremes

All-time high in 1959, all-time low in 1941: 35.9°C / 18.0°C.

One bar per year of total rainfall. Dashed line is the long-term average. Normal = the average annual rainfall across every year of record (1940–2026).

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 normal 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). Normal = the long-term average for that calendar date (1940–2026).
