What this means for your bag
Short days and fast temperature drops after sunset change what you pack. These get pre-ticked in the packing tool for your dates.
Headlamp
Early darkness means hands-free light for walking and photos.
Insulating layers
Temperature falls sharply once the sun is down — layer up for evenings.
Reflective / hi-vis
Long dark hours mean walking roadside in low light — stay visible.
Eye mask
Flip side in summer: light near midnight makes sleep hard — pack for June.
