BIG OUTDOOR DIVORCE PARTY

Now, what in the world is pathetic about having a big outdoor party after a divorce?! I would like to know because each and every year since 1990, I celebrate "my" Divorce Day! I cannot see myself mourning over a marriage we both found out was not meant to be. Therefore, hibernating in my room drenched in tears is not going to happen. Note that you posted a hater comment, and hater comments are only made by someone feeling envy for something they wish they were bold enough to do their very own self... (It's ok, we understand.)

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.

Weather in Berkeley

There is a lot less fog in April than July. We were overseas guests may appreciate sightseeing without the heavy fog

Go with the April date,

Go with the April date, guests always love to be cooler rather than hotter. :)

Choose April

It will be extremely hot for your wedding guests from Ireland in July. I can't stress that enough. The summers here are very different and too warm for a July wedding in my opinion, especially w/o AC. It'd be miserable. I recommend April.

....Choose April

To add.....A heat wave in Ireland is 77°, Berkeley in July is at least this temp. April is the best option.
