Seattle or Washington DC?

3,739 km apart, both in United States. Each is scored month by month on the same ten years of climate readings, the public holidays that crowd it, and what the flight costs. This is where they part, and when.

Month by month

• Sweet spot
• Good
• OK
• Avoid
• Busy

Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high and its rainy days ("11d": days with at least 1 mm of rain, as a weather station counts them). The pick goes to the better verdict; with the same verdict, to the higher score, unless the two are within a whisker of each other, when it is either. A month both would avoid is neither. A dot marks a busy month.

Before you go

Both are in United States, so the currency, the plugs and the travel advice are the same: type A and B plugs, driving on the right, paying in the United states dollar. Everything for United States.

On arrival

• Apps — Rides: Lyft, Uber. Maps: Google Maps, Apple Maps. Messages: Text messages (SMS), WhatsApp. In San Francisco, Los Angeles, Miami and some other cities you can also book a driverless Waymo in its own app.
• Paying — Cards, Apple Pay and Google Pay work almost everywhere, though a few small places take cash only. Keep some $1 and $5 notes for tips; Venmo and PayPal are for locals.
• UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
• Getting around Seattle — Tap a contactless bank card or phone on ORCA readers on Link light rail, buses, Sounder, the streetcar and Water Taxi (full adult fare). Not on the Monorail or state ferries.
• Getting around Washington DC — Tap a contactless bank card or phone at a Metro Rail faregate to enter and the same one to leave, and at the farebox as you board a Metro Bus. A Smart Trip card works too, and buses take exact cash.
• Tipping — Expected: 15–20% in sit-down restaurants (18–20% is standard in New York) and 10–20% for taxi, Uber and Lyft drivers. Large groups may find it already on the bill.
• Emergency — 911 (any emergency).
  TravelCharika is not an emergency service: we cannot call for help or send anyone. Numbers can change; if one fails, ask someone local or your hotel.

Between them

3,739 km as the crow flies, about 5h 29m in the air.Nonstop · 3 airlines.

The flight time is estimated from the distance. A nonstop or a road is named only where a record has it — nonstop routes from Wikipedia's airport articles (CC BY-SA 4.0), roads from openrouteservice.org by HeiGIT — and none of it is a fare; the searches on each destination's page are where prices live.
