I have compiled a summary of predictions for the 2010 desert wildflower season from a variety of websites, visitor centers and hotlines. Due to budget cuts most California state parks have greatly reduced services and less information is available. Best current sources of information are the websites listed on the “Wildflower Reports” page above. All predictions are tentative as wind, excessive or lack of precipitation, and severe hot or cold can change everything. I will re-post in a week with updates. Please feel free to submit any additions in the comments section below.
Amboy Crater (near Amboy, CA and Route 66): Good rainy season. Early March.
Antelope Valley Poppy Reserve: No official prediction. Website states; “Wildflower blooms occur generally from March through May. The peak viewing period is usually mid-April.” Reserve is closed to all vehicles until at least March 1; gate is open to visitors entering on foot. They will have updates later in season at their website.
Anza Borrego: Ample rainfall this year. Predictions have been very good. Peak predicted for last week of February though the second week of March.
Carrizo Plain: peak blooms will be in mid-march
Tejon Ranch/Hungry Valley/Gorman/Tehachapi/: No posted predictions. Best guess looking at past photos is March and April and maybe into early May
Death Valley: Predicting a moderate season with a peak at the lower elevations in late March to early April
Joshua Tree: Wildflowers are on the slow side due to a lack of fall rain. Good winter rains may result in later bloom.
Mojave National Preserve: Good rain. Looks like a good year for wildflowers. No current predictions for peak time. If you are thinking about going you try calling the park at (760) 252-6100
Red Rock State Park: Rain good so far, will need more over next few weeks. Most likely peak will be end of March into April, but to early to know for sure.
Short Canyon: Had good rains. Best blooming period should be the end of March to April
