The weather at GMARS can be quite variable. If you're planning on visiting GMARS and if you're not familiar with the Southern California desert, it's a good idea to study this section of the RAS website, especially the Trend Graphs page. It'll show you what the wind and temperature have been doing for the last 24 hours.

GMARS current and historical weather data is provided by the club's Davis Instruments Vantage Pro2 weather station mounted on the GMARS West property. Forecast links go to Weather Underground and the National Weather Service websites. Lunar information is provided by Der-Mond.de.

This page, the Trends page, and the forecast links should provide you with plenty of data to allow you to plan (or cancel) your trip to GMARS accordingly.
