Microclimates & Ballpark Factors

While San Diego is famous for ideal year-round weather, Petco Park’s proximity to San Diego Bay (just a few blocks southwest) creates distinct playing conditions:

• The Marine Layer: For night games in May and June (“May Gray” and “June Gloom”), a dense marine layer rolls off the Pacific Ocean around dusk. Temperatures can drop quickly from 70°F at first pitch down into the upper 50s by the 7th inning.
• Wind Patterns: Afternoon day games typically feature a 7-12 mph breeze blowing in off the bay toward right-center field, suppressing long fly balls. By night, the wind usually dies down completely.
• Humidity & Ball Flight: Heavy evening humidity increases air density, causing deep fly balls to stall out near the warning track compared to afternoon day games.

Rain

We don’t talk about rain-o, no no no.

Most teams have more rainouts in a single season than Petco Park has had in its entire existence. The Padres average about one rainout every 6 to 8 years.

To be exact, there have been a total of four rainouts at Petco Park in its history:

• April 4, 2006 vs. San Francisco Giants
• July 19, 2015 vs. Colorado Rockies
• May 7, 2017 vs. Los Angeles Dodgers
• August 20, 2023 vs. Arizona Diamondbacks (rescheduled due to Hurricane Hilary)

That was 3,394 days between the first and second rainout at Petco Park. During that span, the Padres played 820 consecutive days of games in the sun.

Padres Rainout Policy

If a game is ruled a “rainout”—meaning weather forces the game to be terminated before it becomes an official game—it will be rescheduled. An official game (5 innings completed, or 4.5 if the Padres are leading) will not be rescheduled. A ticket to a rained-out game becomes a “rain check.”

If the replacement game is rescheduled to a standalone date, your tickets (rain checks) remain valid for the new game date, and you keep your original seats.

If the game is rolled into a single-ticket doubleheader, you can exchange your tickets at the Advance Ticket Windows at Petco Park for any available regular season game of comparable value.
