Rain days are the days with at least 1 mm of rain, as a weather station counts them.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest from May to July; quietest from October to December.

Then and now

Yellowstone's December days now average -3.4°C, 2.6°C warmer than in 1981–1990. 2 of 12 months are clearly warmer.

The drive from each airport is the road's, from openrouteservice.org by HeiGIT: typical, not a schedule.

How far Yellowstone is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Being there

  • 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.
  • 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.

Getting around Yellowstone

  • 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.

A useful way to orient yourself is to visualize the roads inside Yellowstone as making a "figure-8" shape. More on Wikivoyage

The year in Yellowstone

Yellowstone can experience unpredictable weather, especially in early spring and late fall, so visitors should be prepared for various conditions.

Busiest
mid Jun to late Aug — Warm weather and full park access attract the most visitors.
Quieter, still good
mid May to mid Jun — Springtime blossoms and moderate weather provide a pleasant experience.
early Sep to mid Oct — Foliage changes and cooler temperatures lead to fewer crowds.
Watch out for wildfire season; extreme heat

Written by a language model from the climate figures above. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe.
