Wedding in April versus July in Berkeley, CA

Hi,

We are planning a wedding for either April 18th or July 3rd, 2019 in Berkeley, CA. This seems to say that the summer months may be warmer than normal. Do you think it will be too hot in July for our guests who are from Ireland? As you know, many homes and buildings in the Bay Area don't have air conditioning. So we are wondering if we should switch from our July date to April. The wedding is at an outdoor/indoor venue and I'm not sure if the indoor hall has air conditioning.

Thanks for your thoughts,
Brooke

Berkeley Weather

Berkeley never gets 'hot'. Very few days in the 80's and super rare would be in the 90's. Either month is great weather. Congratulations!!

Berkeley weather

Also depends on venue. I went to a wedding at the Brazilian room in July during a heat wave. No AC. No fun, especially since i was 8 months pregnant. If there’s AC, July should be fine. April would be nice as well.
