Best Weather in the U.S. This Week 

Where is the best weather in the United States right now? This page ranks cities nationwide by Perfect Weather Index (PWI) score — a daily comfort rating from 1 to 10 that combines temperature, sunshine, humidity, wind, and precipitation. Rankings update each morning using National Weather Service forecast data, so the cities you see reflect today's actual forecast conditions, not historical averages.

What Does a High PWI Score Mean This Week?

A PWI score of 8 or higher means genuinely excellent outdoor conditions — the kind of day most people would describe as perfect weather. Scores of 9 or 10 are rare and reflect an exceptional combination of comfortable temperatures, clear skies, low humidity, calm winds, and no rain.

This week's highest-scoring cities are typically found in:

• The desert Southwest (Arizona, Nevada, New Mexico) — especially in spring and fall when temperatures are mild and skies are clear
• California's coast and foothills — moderate temperatures year-round with low humidity
• The Mountain West at elevation — cooler and drier than the plains in summer
• The southern Plains and Southeast — during fall and winter when heat and humidity have cleared

The lowest-scoring cities this week are usually experiencing active storms, excessive heat, high humidity, or persistent cloud cover.

Why Some Weeks Look Different Than Others

Weather comfort varies dramatically week to week and season to season. In early May, much of the country scores well — spring temperatures, low humidity, and stable high-pressure systems push PWI scores up across a wide geographic range. In mid-July, the same map looks very different — heat and humidity dominate the South and East while the Mountain West and Pacific Northwest emerge as the comfort leaders.

For longer-range planning beyond the 7-day window:

• Best Weather by Month — see when and where conditions are most reliable throughout the year
• Best Weather by State — narrow rankings to your region
• 7-Day Weather Maps — see PWI scores across the entire country as a color-coded map
• National Parks — 7-day PWI rankings for every major U.S. national park

Each location receives a daily Perfect Weather Index score from 1 (poor) to 10 (perfect). Scores are calculated using forecast data from the National Weather Service, focusing on weather conditions most people describe as “nice.”

Cities are ranked using both raw scores and population-aware adjustments

States are ranked using average scores across the forecast grid

Weather preferences vary, but this approach captures conditions that tend to feel comfortable to the widest range of people.
