Berlin caught me off guard. I landed in late October thinking autumn coat weather — got 3°C with sleet instead. Pack serious thermals November-March; layering is non-negotiable. My sweet spot discovery: last two weeks of May. 20°C, beer gardens open, 16 hours of daylight, and flights are still cheap. Skip August — humidity spikes and half the city leaves for holidays. September is gorgeous but bring a jacket by week three. Always carry a foldable umbrella; the rain sneaks up.
