May in San Jose, CA: peak season for golf — great conditions and a wide playing window. Best tee times: mid-morning through early afternoon.
| Average May Weather | |
|---|---|
| Avg daily high | 76°F |

| Rainy days | 5 / mo |
| Avg peak wind | 14.2 mph |
May sits squarely between a cool, unsettled April and a dry, warmer June, and understanding that position explains exactly what you're getting on the course. The high climbs to 76°F — a full 7°F above April's average — while precipitation holds steady at 5 days, identical to last month. That temperature bump is meaningful: mornings start around 53°F, so the 23°F daily swing means your first few holes play noticeably cooler than your back nine.
The tradeoff for all that pleasant warmth is wind. At 14.2 mph peak, May is the 3rd-windiest month of the year in San Jose. You'll feel it most on exposed parkland and links-style layouts in the South Bay. Still, the combination of reliable skies and comfortable afternoon temperatures earns May its Peak Season badge without much debate.
Book morning tee times (before 9 AM) to avoid the afternoon wind peak, which at 14.2 mph can genuinely affect club selection on longer par-4s. May is peak season demand, so reserve weekend slots at least two weeks out — courses fill faster than the April data alone would suggest given the improved temperatures. See how conditions rate hour by hour on our playability scale.
Coming out of April, the 7°F jump in average high makes afternoon rounds genuinely comfortable where they were merely tolerable before, though precipitation stays flat at 5 days so don't expect dramatically drier fairways just yet. Heading into June, the real shift is rainfall: precip days drop sharply from 5 to just 1, making June the cleaner choice if dry conditions are your priority. Wind actually ticks up slightly into June (+0.7 mph), so May's 14.2 mph peak isn't a problem you escape by waiting.

Yes — May earns a Peak Season rating with a 76°F average high, 53°F lows, and only 5 precipitation days. Afternoons are comfortably warm without the heat stress that can arrive later in summer. The main caveat is wind, which peaks at 14.2 mph, making it the 3rd-windiest month of the year.
May's 14.2 mph peak wind is 1.2 mph higher than April's 13 mph, and June climbs another 0.7 mph to 14.9 mph. So wind gradually increases as the season progresses. If calm conditions are important to you, early morning tee times in May are your best hedge — afternoon rounds on open courses will regularly feel that breeze.
