The Bay Area will experience a warm start to June, with Monday and Friday being the hottest days, followed by a significant cooldown over the weekend. - Monday: inland East Bay highs in upper 80s to 90s, South Bay mid-to-low 80s.
- Tuesday: temperatures drop 6-8 degrees as marine layer returns. - Friday: peak warmth again, 3-4 degrees hotter than Monday, with East Bay reaching 90s.
- Saturday: 10-12 degree cooldown, coastal drizzle possible. Near the coast, temperatures remain in the 60s to low 70s throughout the week.
This pattern of alternating warm and cool spells is typical for early June due to the jet stream staying north.
