What to pack for London in October

12 rain days a month finds every seam. A real shell, not a windbreaker.

Wear one, dry one. Cotton stays wet all week here.

The layer you'll wear more than any other.

Check ankles and, if there's a dog, paws and ears every night.

Wet conditions and long sightseeing days strain feet and joints.

This country runs on Type G. Get one with USB-C so you're not fighting over the single outlet.

October daylight runs just under 11 hours, draining phone batteries fast.

Set it up before you land. Signal drops for long stretches outside cities.

Dark by 6:05pm. Every campsite chore after that is a two-hands job.

Twelve rain days in October mean wet streets and layered packing, so overhead capacity matters more than checked luggage.

Ten-hour days of walking require a daypack for layers and snacks.

Fits the overhead on every airline that matters. Skip the checked-bag line entirely.

For the passport, the chargers, and the one dry pair of socks.

Tap water is safe, so a bottle cuts plastic waste.

One brick charges the laptop, phone, and camera.

Hotel and cafe wifi is shared with everyone else in the building. A VPN keeps your banking and email to yourself.

International travel and busy stations increase luggage theft risk.

Two weeks of travel fits a carry-on when clothes are cubed.

Humidity at 83 percent makes clothes smell fast between washes.

Noise on trains and in hotels disrupts rest during short nights.

Rain hits 12 days this month and seeps through regular shoes.

Crowded transit and public spaces mean frequent hand contact.

One power bank charges multiple devices at a single outlet.

Crossing into Europe requires passport checks at multiple points.

Checked bags on international flights need locking.

Hanging bags save space in tight guesthouse bathrooms.

Transit sleep on planes and trains matters for jet lag.
