What to pack for Telluride in September
Heading to Telluride in September? Here's a packing list built directly from local climate averages — not generic blog advice.
September is mid-pack for warmth in Telluride (ranked 4 of 12) and moderate for rainfall (ranked 9 of 12). Day temperatures are 3°C cooler than August and cooling toward October — so this month's packing list won't be identical to August's or October's.

Power, voltage & adapters
- ★ 120V at 60Hz Mains electricity standard for United States
- ★ Plug types: A, B (Type A — flat 2-pin (US/Canada/Japan style)) Most common: A. Older buildings may also use B.
- • From the UK/Ireland: bring a G→A travel adapter UK Type G plugs don't fit United States's outlets
- • From continental Europe: bring a C/F→A travel adapter EU Type C/F plugs don't fit United States's outlets
- • If your device is labeled '220–240V only' (common for European hairdryers/kettles), it WILL underperform or not work at all here. Most phone/laptop chargers are dual-voltage — they're fine. United States runs 120V — too low for EU-only 230V devices
- · Easiest option: a universal travel adapter (e.g. Anker, Epicka) that handles A/B/C/E/F/G/I in one — covers ~95% of countries. If you travel to multiple regions
⚖️ Can you carry-on?
Maybe — possible with a packable down jacket, careful shoe choices (one warm + one walking), and wearing your bulkiest layer on the plane. Expect to use most of the carry-on volume.
