March into this season

Typically in San Jose, March’s temperatures fluctuate between an average low of 43° and high of 62°, but expect to see more rainfall this year. The most rainfall comes during this month, and averages around 9.8 days. Pro tip: Get an extra hour of daylight when daily saving time begins Sunday, March 12, at 2 a.m.

April’s outlook

This month’s weather won’t deviate much from March’s, with average high and low temps between 66° and 45°. There will likely be less rainfall, and more sunshine with an average daily maximum UV index of 5 — so stay protected with sunscreen on your Alum Rock hikes.

It’s gonna be May

Temps continue to rise as our daily high averages around 75° — which we think is perfect hiking weather. The 53° nightly temps and 12 mph winds also make May nights the beginning of our opening-a-window-right-before-bed season (whenever it’s not too windy).
