Stormy weather...Please understand that launch dates/times are tentative and are subject to change without notice. If adverse weather conditions occur during the week before a launch, then it’s the flyer’s responsibility to get accurate lake bed conditions before heading out to a launch as a cancellation can be made as late as the morning of the launch!

Weather updates may be posted on this web site and on Facebook when relevant information is available. Updates will be posted as needed.

PLEASE NOTE! The weather AT THE LAKEBED may not match surrounding areas, even as close as Victorville or Apple Valley. When we post weather updates, they will be for the lakebed. Other sources may be too general to give an accurate  indication of conditions at the launch site. While we cannot offer any guarantee that our forecasts are going to be perfect–if you rely on other sources for information we can’t be responsible for their accuracy. We have had many instances of people deciding not to come to a launch due to weather conditions, only to find out that the lakebed had great flying weather!

We do the best we can to announce the launch status and conditions at the site. Sometimes, you may not get the word. Please understand that most of us have had the experience of going to the site, only to find out that it is too windy or the lake bed is too wet. We don’t like to find out that way either!

Leslie Seiders has this to say about Lucerne weather:

“Generally, when there is a Santa Ana condition, or high pressure in Nevada, the High Desert is relatively calm. This is because we’re on the high side of “the dam break”, meaning the passes in the mountains. If there is low pressure in Nevada then usually there are windy conditions above the passes in the high desert as we are now on the downward side of the “dam break”.

“Depending on where the low pressure is located I can have very windy conditions above the Cajon Pass, here at my house, and totally calm conditions at the Lakebed. In essence, the nozzle of the pass is not pointed toward the Lakebed. This is the same for the Santa Ana. Depending were the nozzle is pointing, you can have windy conditions in Riverside and calm conditions in Ontario or Vice Versa.

“Another way to determine if there is “W” is to examine the isobars on a weather map. If they are far apart then it is usually calm. If they’re close together then it is generally windy.”
