What to Wear in San Jose in May
May in San Jose offers the best of Silicon Valley spring, with temperatures from 54°F to 76°F, sunny afternoons along Santana Row's alfresco dining promenade, and only about 2 rainy days standing between you and near-perfect outdoor conditions. Morning temperatures are cool enough for a light jacket along the Guadalupe River Park trails, while afternoons warm comfortably enough for a single-layer linen or cotton outfit. UV protection is important — the valley's clear skies and strong sunshine mean even moderate exposure adds up.

Navigating San Jose's May weather requires smart layering, as this month ushers in famously pleasant days with significant daily temperature swings. Typically, you can expect mild to warm afternoons, often reaching the low to mid-70s°F (21-26°C), perfect for exploring. However, mornings and evenings remain distinctly cool, frequently dipping into the low 50s°F (10-15°C). While the famed "May Gray" can bring overcast skies in the mornings, these usually burn off by midday, revealing abundant sunshine.

Think light blouses or t-shirts for the sunny afternoons, paired with a reliable light jacket (denim, bomber, or a cardigan) for the cooler parts of the day. Comfortable pants like jeans, chinos, or even a maxi dress with a cover-up are ideal. Closed-toe shoes suitable for walking, along with sunglasses and sunscreen, are essential to truly enjoy San Jose's charming May weather.
