When Was the Last Time It Rained in Cupertino? The Answer Might Shock You

Cupertino Weather Snapshot – Key Information

Cupertino has been blessed with clear skies and warm, dry air that sticks to its tree-lined boulevards like a seasonal uniform for the past month. As of June 29, 2025, not a drop of rain has been observed. Even though the majority of the population is accustomed to this kind of weather, the extended dry spell has made it so difficult for locals to remember what a summer rainstorm actually feels like.

Cupertino’s skies have been unusually calm over the last 30 days, with cloudless blue hues painting the sky every day. According to daily weather records, there is no indication of precipitation, not even a drizzle at dawn, and sunny highs of up to 93°F. June hasn’t historically been thought of as a particularly rainy month for the city. However, the complete lack of moisture—combined with the increasing temperatures—has become much more apparent.

The last time June saw significant precipitation was in 2011, when 0.3 inches fell on the 28th. Since then, there has never been any rainfall on that date in Cupertino, year after year. The city has experienced prolonged dry seasons with little interruption over the last ten years, becoming remarkably similar to other drought-prone regions of California. The dryness is now expected rather than just the norm.

Residents, especially those who have lived there for a long time, remember the sudden summer showers that used to cool sidewalks and turn lawns green for a short while before the heat returned. But these kinds of moments seem more and more uncommon these days. It’s likely that younger generations—particularly those attending Cupertino Unified schools—have never had to walk home in the rain in June.

The fact that Cupertino’s seasonal weather pattern is shifting toward increasingly severe dryness with each year is made abundantly evident by consulting websites such as Time and Date and Weather Underground. The city’s typical wettest month, February 2025, did see some rainfall, but even that felt unusually short. Many locals didn’t even bother to get their umbrellas out.

Concern over declining annual precipitation totals in California’s coastal tech cities has grown in recent days, according to climate scientists. The absence of rain has special repercussions for cities like Cupertino, which is located directly west of Silicon Valley’s data centers and startup headquarters. Given its Mediterranean climate, which is already prone to protracted dry spells, any further decrease in rainfall puts additional strain on the local water table and increases the risk of wildfires in the hills nearby.

The forecast appears to be accurate based on the daily reports from Cupertino over the past few weeks. The upper 80s and lower 90s are the usual highs. At night, the humidity only slightly increases. No rain, no dew, and no sign of impending storms are present. Although this consistency is far from typical by historical standards, it may be remarkably effective for those organizing events, bike commutes, or hikes at Fremont Older Open Space Preserve.

Cupertino has responded by making calculated investments. The city’s public infrastructure has significantly improved; highly effective water systems and drought-resistant landscaping are now typicalplace. Even these developments, though, are only partially able to counteract environmental change. Long-term sustainability is called into question when there is no natural rainfall for weeks or even months.

When it comes to environmental projects, the tech community in Cupertino is especially creative. Large corporations with local headquarters have created smart landscaping systems, rooftop solar panels, and water recycling technologies. However, the land still requires sporadic rainfall to cool the ground and replenish aquifers in spite of these efforts. Clouds cannot be called by any algorithm.

The current drought in Cupertino is not unusual when compared to larger climate trends. However, it is distinctly visible. The city receives disproportionate media and political attention because it is home to Apple and many well-known executives. Being in the spotlight presents a chance to take the lead in climate action as well as technology.

Naturally, Cupertino’s dry climate is advantageous to its way of life. Local businesses thrive on a consistent calendar of sunshine, public parks stay open, and outdoor cafes stay open late. However, that ease conceals an increasing susceptibility. Concern has even been subtly voiced by fire officials. Regional alerts warned of a high risk of fire by mid-spring, extending from Sunnyvale to Los Gatos.

People spent more time outside than ever before the pandemic. Many people realized how important weather is to routine, mood, and health as a result of that change. However, in a year like 2025, when June has gone by without a single drop, it is evident how much communities depend on routines that we once took for granted. These days, Cupertino’s drought is turning into one of those pivotal moments.

It’s getting harder to determine when it last rained for Cupertino locals without consulting weather archives. And maybe that’s the idea. Data logs and dinner-table nostalgia have quietly turned the rain into a memory in a city at the forefront of technology.

Forecasts for early July indicate that there will be more sunshine and no chance of rain. However, the weather serves as a signal as well as a backdrop. Although the dry spell may not cause panic right now, its continued existence calls for a more thorough examination of sustainability planning. Cupertino can continue to be resilient with the help of remarkably successful conservation initiatives and strategic citywide coordination. Nevertheless, there has never been a more pressing need for natural rainfall—reviving, healing, and necessary.
