Mineral King to Mt. Whitney

This is textbook Sierra spring weather — sunny skies and mild temperatures through Tuesday with no precipitation in the forecast. Highs in the low 50s and lows in the mid-30s mean comfortable hiking conditions and manageable overnight temps without extreme cold gear requirements. Light northwest winds under 10 mph won't create any exposure issues on ridges or exposed terrain.

Water situation is actually favorable for backpacking right now. All monitored streams are running below normal (41-88% of median flows) with most trending stable or falling. This means stream crossings will be straightforward, but also means reliable water sources along your route. The below-normal flows indicate no recent significant snowmelt pulses, so you won't encounter the swollen, dangerous crossings that can plague Sierra routes during heavy melt periods.

Snowpack data shows interesting regional variation — Annie Springs at 6,000 feet has 33 inches with falling trends, indicating active settlement and consolidation. The deeper pack at Long Lake (92 inches) is also trending down, suggesting stable melt patterns rather than rapid warming events that could destabilize conditions or create flash flooding downstream.

Plan for standard March Sierra conditions with potential morning frost giving way to pleasant hiking temperatures by mid-morning. No active fires within 50 miles means clear air quality throughout your trip. The 12-hour daylight window gives you plenty of flexibility for daily mileage without forced early starts or late finishes.
