🌡️ Temperature

Think warm. Expect to see warmer-than-normal temperatures across much of the US, with the exception of the Midwest. The predicted continuation of La Niña conditions plays a large role in the expected hotter-than-average temps in June-August for the US, especially for us in the West.

In San Jose, there’s a 40-50% chance of our high temperatures being above normal. Usually, San Jose averages highs of 80° in June, 82° in July, and 82° in August.

No AC? No problem. In the case of extreme heat, you can take advantage of one of the many cooling centers in Santa Clara County.

🌨️ Precipitation

You probably won’t need that umbrella. Usually, San Jose averages zero days of rain in June, July, and August — and it doesn’t look like this year will be any different.

⌛ Drought

Santa Clara County is experiencing its driest year since 1977, and unfortunately, we’re in the midst of a severe drought emergency — which is likely to continue through August.
