Yosemite’s climate changes significantly throughout the year. Spring (April-May) temperatures in Yosemite Valley typically range from 50-70°F (10-21°C). Higher elevations remain cooler, with snow still present. Early spring sees high precipitation, which benefits waterfalls, leading to their peak flow. Snowmelt impacts road access; Tioga Road and Glacier Point Road usually open in late May or early June, depending on snowpack.
Summer (June-August) Yosemite Valley temperatures commonly range from 70-90°F (21-32°C), with cooler nights. Precipitation is low during these months. The high country, including Tuolumne Meadows, becomes fully accessible, opening up more hiking and exploration opportunities. July and August bring peak heat. Afternoon thunderstorms are possible, especially in the high country, so be ready for quick weather changes.

Snowfall is common from November to May. It impacts road access, often needing tire chains or 4x4 vehicles. Always check current road conditions before travel, as they change quickly. Yosemite and surrounding areas are prone to wildfires, especially in late summer and fall. Air quality experiences smoke, and park access limits or closes certain areas for safety. Stay informed via park alerts.
Rarely, heavy rain combined with rapid snowmelt creates localized flooding, especially in Yosemite Valley. This is not common but impacts low-lying areas near rivers. For waterfalls, late spring (April-May) is ideal. High country hiking is best in summer (July-September) when Tioga Road is open and snow has melted. Backpacking offers best weather mid-summer to early fall (July-September). Rock climbing finds moderate temperatures in spring and fall. Winter (December-March) is the time for skiing and snowshoeing.

International visitors must comply with standard U.S. Visa regulations. Many countries participate in the Visa Waiver Program (VWP), allowing their citizens to travel to the U.S. for tourism or business for up to 90 days without a visa. These travelers need an approved Electronic System for Travel Authorization (ESTA) before departure. Citizens of countries not in the VWP must obtain a B-2 tourist visa. Apply for visas well in advance through a U.S. Embassy or consulate in your home country. The U.S. Department of State website details accurate, nationality-specific requirements.
For entry into the U.S., you need a valid passport. It remains valid for at least six months beyond your intended period of stay. If you need a visa, present your approved visa. If traveling under the Visa Waiver Program, ensure you have your approved ESTA. For visa application services, consider VisaHQ.
Yosemite offers many activities that need special permits to manage visitor impact and preserve wilderness quality.
Day hikers who wish to ascend the Half Dome cables must obtain a permit. This permit is extremely competitive and allocated via a pre-season lottery in March. A smaller number of permits are also available through daily lotteries during the hiking season, held two days before the intended hike date. Without a permit, you cannot ascend the cables.
Held in March for most permits.
A limited number of permits released two days before the hike date.
Available via lottery 24 weeks in advance for overnight trips.
Securing permits can be very competitive due to high demand.
Ascending the Half Dome cables without a valid permit is not allowed.
The currency used in the United States is the United States Dollar (USD). ATMs are available in Yosemite Valley at major lodges and some general stores. They are also present in gateway towns. Credit cards are widely accepted throughout the park and surrounding areas. For international travelers, inform your bank of your travel plans to avoid card holds. Consider a travel credit card with no foreign transaction fees.
Accommodation: Camping is the most affordable option ($30-$40/night per site). Budget lodging outside the park ($100-$150/night) splits among occupants.
Accommodation: Mid-range lodges inside park ($250-$400/night). Hotels just outside ($180-$300/night).
No specific vaccinations are needed for entry to Yosemite National Park. Standard U.S. Recommendations apply, like keeping your Tetanus vaccination up-to-date. Consult your doctor for personal health advice before travel.
Altitude Sickness: For those visiting higher elevations (Tuolumne Meadows, Glacier Point), take time to acclimatize. Ascend gradually, stay hydrated, and avoid strenuous activity on your first day. Headaches, nausea, and dizziness are symptoms. Dehydration: A serious concern, especially during summer hikes. Carry plenty of water. For backcountry trips, carry a Water filter or purification tablets.
Sunburn/Heat Exhaustion: The Sierra Nevada sun is intense. Use High-SPF sunscreen, wear sun-protective clothing, and avoid strenuous activity during midday heat. Rest in shade and drink water.
For all emergencies (fire, police, medical), dial 911. Cellular service limits in many areas; landlines exist at lodges and visitor centers. Park Rangers are trained in wilderness rescue and first aid.
Yosemite Medical Clinic (209-372-4637) offers urgent care in Yosemite Valley.
Nearest full-service hospitals are outside the park (Mariposa, Sonora).
Treated tap water in developed areas (lodges, campgrounds) is generally safe to drink. Backcountry water sources always need filtration, purification, or boiling to prevent waterborne illnesses.
Treated tap water is available and safe.
Never leave food unattended; bears learn quickly.
Wildfires are the most significant hazard, especially late summer and fall. Monitor park alerts. Rockfall/Landslides occur frequently in Yosemite Valley due to steep granite cliffs. Be aware of signage. Falling trees also pose a risk during high winds or heavy snow.
Yosemite is generally safe; most crime is opportunistic vehicle break-ins.
Always lock your vehicle; do not leave valuables visible.
