Typical high / low (°F) and days with rain or snow, 1991–2020. Measured at Berkeley, CA, 1.1 mi away at 310 ft. The station sits about 1,000 ft lower than this place, so expect it a little cooler here. Source: NOAA NCEI U.S. Climate Normals 1991–2020.

Diagonal Traverse Rock is a climbing area in Tilden Regional Park in California, on regional agency land. It sits among several other climbing spots and trails, so it's easy to fold into a longer outing in the park. The most comfortable months for a visit are late spring through early fall. Typical averages from a nearby weather station in Berkeley show highs around 70°F in May and 76°F in September, with only a day or two of rain each month from June through September. That station sits well below the park, so temperatures at the rock run cooler. Main Rock and Short Traverse Rock are both about 0.1 mile away. The Upper Jordan Fire Trail starts just as close, and the Grizzly Peak Trail is about 0.2 mile off.
