Recreational Weather for Mammoth Mountain & the Eastern Sierra​

Friday 5-20-22 @ 5:06 AM – Good morning, it’s a cool and windy Friday morning here in the Eastern Sierra.

At this time Mammoth Mountain has gusts out of the SW to 75 MPH with gusts to 23 MPH down in Mammoth Lakes. The Crowley Lake area is showing wind speeds at 7 MPH this morning. 

Down in the Bishop and Mill Pond Areas, there are wind gusts out of the north to 40 MPH with very dusty and haze skies.

If you heading out for an adventure today expect clear skies everywhere except at the top of Mammoth Mountain this morning.

Highs will be cooler with the winds slowly backing off during the day. Areas that have haze and dust won’t clear out to Saturday when I NE flow should bring a return to the clear blue skies.

For the weekend the weather is set to be great with much lighter winds expected along with high temperatures that are close to the average for this time of year.


Here are the links to the specific highs, lows, and wind speeds for many of the major recreation points in the Eastern Sierra: Mammoth Mountain Main Lodge, Top of Mammoth Mountain, Mammoth Lakes, June Lake, Crowley Lake, Toms Place, Rock Creek Lake, Bishop & Mill Pond, South Lake.

10 Day Weather Summary: The cooler windy weather that was forecast has arrived with the low pressure system sliding to the east of the area once again. As the system moves to the east there will be a NE flow on Saturday bring in clear blue skies.

The NE winds along the ridge tops will be in the 35-40 MPH range Saturday, winds at all other elevation will be much lighter.

Most of the haze and dust down in the Bishop and Mill Pond area should move out by early Saturday.

By Sunday the Eastern Sierra will be under a light NW flow that will turn to the SW as the next strong ridge of high pressure moves into the area by Monday. High will rapidly come up as the ridge takes over on Monday. This will be the start of some great weather to get out for an adventure here in the Eastern Sierra.

For Tuesday into Thursday that ridge of high presure will bring highs well above average with a high of 80 possible in Mammoth Lakes by mid week with the Bishop / Mill Pond areas into the upper 90s to 100.

After that? A next inside slider  system will dig in and bring windy and cooler weather with even a possible chance of a shower for the high country over the Memorial Day weekend.

Here is the Ensemble showing the chance of the showers that was mentioned above.

That precipitation would be a dusting of the snow over the higher elevations and up in the back country.

Something to watch if you’re coming up for the Memorial Holiday weekend.

Below is the Temperature Anomaly Ensemble Mean over the next 10 days.

When you see the red over California it’s going to be warm in the High Country and Hot in Bishop mid day. The blues are the cooler temperatures that bring relief from the warmer days.

I hope to see you out in the area mountain biking or getting some morning turns in real soon.
