Packing & comfort index
Choose a US city and a month and this free tool classifies the typical weather — Cold, Cool, Mild, Warm, Hot or Very hot for temperature, and Dry through Very wet for rainfall — then suggests what to pack. It reads the same NOAA 1991–2020 average high, low and precipitation shown on each city page, for 40 cities. It is a climate average, not a forecast.

How the bands are defined
Temperature is banded by the month's average daytime high: under 40°F is Cold, 40–55°F Cool, 55–70°F Mild, 70–85°F Warm, 85–95°F Hot and 95°F-plus Very hot. Precipitation is banded by the month's average total: under 1 in is Dry, 1–3 in Some rain, 3–6 in Wet and 6 in-plus Very wet. The thresholds are fixed and applied identically to every city, so two cities in the same band feel broadly similar. Humidity and wind are not modelled.
Frequently asked questions
How does the packing & comfort index work?
Pick a city and a month and the tool looks up that city's NOAA 1991–2020 average high, low and precipitation, then classifies them. Highs are banded from Cold (under 40°F) through Mild (60–70°F) to Very hot (95°F+); precipitation is banded from Dry (under 1 in) to Very wet (6 in+). It then suggests what to pack.
Is this a weather forecast?
No. It uses 30-year climate normals (long-term averages), so it tells you what is typical for a city in a given month — not what the weather will actually be on your travel dates. Always check a live forecast close to your trip.
