Some disagree here. Fair enough.
Introduction
June marks the transition from the lingering chill of late spring to the comfortable embrace of early summer in Grand Teton National Park. Practically speaking, the park’s high alpine environment—reaching elevations above 12,000 ft—creates a microclimate that can differ dramatically from the surrounding valleys. Also, visitors often wonder what to expect in terms of temperature, cloud cover, and rainfall. This guide breaks down the key weather characteristics for June, highlights daily variations, and offers practical tips for enjoying the park’s natural beauty while staying prepared.
Typical Temperature Ranges
| Elevation | Average High | Average Low | Temperature Range |
|---|---|---|---|
| 6,000 ft (Jackson Hole) | 60–70 °F (15–21 °C) | 35–45 °F (2–7 °C) | 25–35 °F (14–19 °C) |
| 9,000 ft (Moby Dick Trailhead) | 45–55 °F (7–13 °C) | 20–30 °F (–6 to –1 °C) | 25–35 °F (14–19 °C) |
| 12,000 ft (Grand Teton summit) | 30–40 °F (–1 to 4 °C) | 0–10 °F (–18 to –12 °C) | 30–40 °F (–1 to 4 °C) |
People argue about this. Here's where I land on it.
- Daytime highs in the lower valleys hover around 65 °F (18 °C), while higher elevations see cooler peaks near 50 °F (10 °C).
- Nighttime lows can drop sharply, especially at 9,000–12,000 ft, often falling below freezing. Even in June, frost and early snow are possible at the highest summits.
- Diurnal variation (difference between day and night temperatures) can exceed 30 °F (17 °C), underscoring the need for layered clothing.
Cloud Cover and Sunshine
- Average sunny days: 70–75 % of the day, though clouds often form early in the morning and clear by mid‑afternoon.
- Sunrise and sunset: Around 6:00 am and 8:30 pm, respectively, giving roughly 14.5 hours of daylight.
- UV index: Moderate to high (3–6) due to the high elevation and thin atmosphere, so sunscreen is essential even on cloudy days.
Why Cloud Patterns Matter
- Morning clouds can obscure the Teton Range, creating dramatic silhouettes as the sun rises.
- Afternoon clearing often reveals the iconic peaks and opens up photo opportunities.
- Evening clouds may return, especially if a low‑pressure system moves in, adding a layer of mystery to sunset vistas.
Precipitation: Rain, Snow, and Thunderstorms
| Type | Frequency | Typical Timing |
|---|---|---|
| Rain | 15–20 % of days | Early morning or late afternoon |
| Snow | 5–10 % of days (high elevations) | Late evening to early morning |
| Thunderstorms | 5–10 % of days | Mid‑afternoon, often short bursts |
- Rainfall averages 0.5–0.8 inches (12–20 mm) per month, primarily falling as brief showers.
- Snow remains possible above 9,000 ft, especially overnight, so high‑altitude hikers should carry crampons and avalanche safety gear.
- Thunderstorms can develop quickly in the afternoons, bringing lightning, hail, and strong winds. Seek shelter in sturdy structures or lower elevations if a storm is imminent.
Wind Patterns
- Average wind speed: 5–10 mph (8–16 kph) at lower elevations; up to 20–30 mph (32–48 kph) near ridges.
- Wind chill: At 9,000–12,000 ft, wind can make temperatures feel 10–20 °F (6–11 °C) colder than the thermometer indicates.
- Microclimates: Narrow canyons and sheltered valleys can experience gusts that blow through in minutes, so hikers should secure gear and be prepared for sudden changes.
Seasonal Highlights in June
1. Wildlife Activity
- Mammals: Deer, elk, and bison are abundant in the valleys, while moose may appear near the lakes.
- Birds: Bald eagles, golden eagles, and a variety of waterfowl thrive near Jackson Lake.
- Bear behavior: Black bears begin to emerge from winter dens, so bear safety protocols remain crucial.
2. Flowering and Vegetation
- Wildflowers: The park’s meadows bloom with lupines, Indian paintbrush, and trillium, creating a vibrant tapestry.
- Alpine flora: High‑elevation plants such as alpine poppy and glacier lilies flourish, but their growth is limited by the short summer season.
3. Trail Conditions
- Clearing of snow: By mid‑June, most lower‑elevation trails are snow‑free, though some high‑altitude paths may still have lingering patches.
- Trail maintenance: The National Park Service often performs upkeep during this period, improving footing and signage.

Rivers and streams run high and cold with meltwater—exercise extreme caution when crossing, and never underestimate the power of swift water.
