Prompt: Act like a weather expert and predict what the weather will be like for Telluride bluegrass festival of 2025. Use past and historical data.
As a weather expert, here’s an informed forecast for the Telluride Bluegrass Festival 2025, based on decades of climate data and regional weather patterns:
Historical Climate Overview (Mid‑June)
The Telluride Bluegrass Festival runs June 19–22, 2025 (Planet Bluegrass).
Temperature
- Daytime highs historically range from 70 °F to low 80s – average July (peak) highs near 73–77 °F; late June typically just a bit cooler (Weather Spark, Mild to Wild Rafting & Jeep Tours).
- Nighttime lows tend to drop to the 40s or low 50s, often between 40 °F and 50 °F (Weather Spark, Telluride Rentals).
Precipitation & Humidity
- Mid-summer in the Colorado Rockies coincides with the North American Monsoon, bringing daily convection and afternoon thunderstorms (Wikipedia, Wanderlog).
- June is relatively dry, but by July, daily rain chances exceed 50%. In late June, expect a 20–30% chance of passing showers, increasing to 40–50% by festival time (Wanderlog, Tourbase).
- Wet days typically bring light showers or brief thunderstorms with a few millimeters of rain—rarely heavy downpours (Wanderlog, World Weather & Climate Information).
Variability in Mountain Weather
-
Weather can shift rapidly: sunny skies can turn to brisk showers or even a snow flurry at night—some years people have camped during “blizzards” and also burned in the sun within the same festival (Festivarian Forum, Festivarian Forum).
-
A long-time attendee noted:
“Plan on anything… hot… down to the 30s/40s at night. Rain can happen at any time and snow is not unheard of at night.” (Festivarian Forum)
Tentative Forecast for June 19–22, 2025
| Time of Day | Typical Conditions |
|---|---|
| Afternoons (~12–4 pm) | Mostly sunny to partly cloudy, temperatures around 68–75 °F. Some years spike near low 80s due to strong sun and altitude. |
| Evenings (5–9 pm) | Cooling quickly into 50s, clear skies possible, but isolated showers or storms may linger. |
| Overnight (10 pm–6 am) | Chilly, low 40s, occasional dips near 35 °F—still a chance of light rain or even graupel at high elevation. |
| Precipitation | Expect 1–2 afternoon showers or thunderstorms during the 4 days—typically brief (30–90 minutes), often followed by clearing. |
| Sun & UV | With ~14 hours of daylight and high altitude, UV is intense. Be prepared with sunscreen, hat, and sunglasses (Wanderlog, Tourbase). |
| Wind | Moderate—typical midday breezes around 8–9 mph, with occasional gusts if storms move through (Wanderlog). |
What to Pack & Final Recommendations
-
Layered Clothing
- Day: Light tees/long-sleeves, sun hat.
- Evening: Warm mid-layer (fleece or wool), possibly a light down jacket for late-night chill.
- Thermals optional if you’re sensitive to cold—some attendees pack thermals and warm tights (Festivarian Forum).
-
Rain Gear
- Pack a lightweight waterproof jacket or poncho—storms come fast and often subside quickly.
- Rain boots or waterproof footwear recommended for muddy trails (from festival forums) (Tourbase).
-
Sun Protection
- Bring high-SPF sunscreen, UV-blocking sunglasses, and a brimmed hat. High elevation amplifies sun intensity.
-
Gear Beyond Clothing
- A refillable water bottle—hydration is crucial at altitude (Tourbase).
- Compact umbrella could be handy, though crowd-walking ponchos are often more practical.
- Be prepared for wind—a windproof layer helps during gusty periods.

Altitude Awareness
Summary
Expect warm, sunny afternoons (70s °F), sharp overnight chills (40s °F), and a few brief afternoon storms or showers, especially later in the festival. Sun protection, warm layers, and rain gear are all essential. Mountain weather is famously unpredictable—prepare for quick shifts.
