The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2025. 2026 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between February and April by looking at the decadal average line positions.
