In Germany, the sun starts getting less strong after the summer solstice , which is usually around June 21. The days still stay long and bright through July, but the peak is already over.

Summer dates

  • Meteorological summer: June 1 to August 31.
  • Longest day / summer solstice: usually around June 21.
  • Noticeably weaker sun: generally from late June into July and August , as daylight gradually shortens after the solstice.

What this means in practice

The sun can still feel very strong in July and August, especially around midday, even though the days are slowly getting shorter after June 21. In many parts of Germany, sunsets are still very late in June and early July, so it stays bright for a long time.

Simple rule

If you want the shortest answer: the sun starts weakening right after June 21, but the difference becomes more noticeable later in summer, especially from July onward.

Short version

  • Strongest point: around June 21.
  • Gradually less strong: after June 21.
  • Clearer drop in daylight: July and August.
