KEY MESSAGES

Updated at 1202 AM PDT Sun Jun 14 2026

- Minor coastal flooding due to higher than normal high tides anticipated across low-lying coastal areas.

- Hazardous beach conditions through Tuesday with increased risk of sneaker waves and strong rip currents.

- Minor to locally Moderate HeatRisk through the middle of the week with seasonable June temperatures.

SHORT TERM

Issued at 1202 AM PDT Sun Jun 14 2026 (Today and tonight)

Marine stratus continues to expand over the San Francisco Bay Area and Central California Coast this early Saturday morning. With the marine layer ever-so gradually deepening over the last few days, interior locations such as Livermore and Concord are finally realizing the marine-cooled influence where temperatures running 4-8 deg F cooler compared to 24 hours ago. By sunrise, expect the classic June stratus for many communities.

The eastern Pacific ridge has been the driving synoptic feature for California over the last several days. This will change today as a weak disturbance develops over NorCal, disrupting the ridge's scope temporarily. While minimal day-to-day changes are forecast along the coast, interior locations can expect several degrees of cooling from Saturday to today. This will result more widespread Minor HeatRisk throughout the Bay Area and Central Coast, with Moderate HeatRisk reserved for the Central Valley and very isolated East/South Bay locations.

High tide coastal flooding will continue to occur nightly along the low-lying areas of the Bayshore and the Pacific Coast through the middle of the week. Tide levels are forecast to rise up to 2.0 feet above normal into the middle of the week. This increase is driven by multiple contributing factors, including Sunday's new moon and lunar perigee, ~ 7 inches of tidal anomaly from storm surge and thermal expansion in the Eastern Pacific, and ~ 2 inches of sea level rise since vertical datums were established in the 1980s/1990s. While lower than the historic tidal flooding in January (which peaked at 2.6 ft), these tides could end up being the highest observed in the summer, beating the current record of 1.7 ft from July 2022.

LONG TERM

Issued at 1202 AM PDT Sun Jun 14 2026 (Monday through Saturday)

Eastern Pacific ridge will attempt to re-establish itself on Monday and Tuesday. Temperatures in some interior locations may subtly nudge upward as a result, but nothing that reintroduces new HeatRisk categories -- still anticipating widespread Minor to locally Moderate. The ordinary marine status should continue to blanket the usual spots through much of the week.

AVIATION

(12Z TAFS) Issued at 428 AM PDT Sun Jun 14 2026

Satellite shows widespread coastal stratus /IFR-LIFR/ including an inland intrusion of stratus /MVFR-IFR/. Inland stratus will mix out to VFR by late morning. Coastal stratus /MVFR-IFR-LIFR/ moves inland tonight and Monday morning.

Vicinity of SFO...Stratus /MVFR-IFR/ is nearby and based on model guidance it'll develop at SFO this morning. Stratus mixes out 17z today and redevelops early Monday morning. West to northwest wind 5 to 15 knots.

SFO Bridge Approach...Stratus /MVFR-IFR/ is in the approach and is forecast to mix out to VFR by 17z today. Stratus redevelops late tonight and Monday morning.

Vicinity of SJC and OAK...Stratus /MVFR-IFR/ is nearing SJC Airport with a tempo ceiling forecast 12z-16z today. VFR for the remainder of the day to tonight then stratus will be nearby Monday morning. For OAK Airport, stratus /MVFR-IFR/ is forecast to prevail to 18z today. VFR for the remainder of the day to mid evening. Stratus /IFR/ prevails tonight and Monday morning.

Monterey Bay Terminals...Stratus /IFR-LIFR/ until late morning, VFR this afternoon then stratus /IFR/ redevelops and moves inland this evening. Stratus prevails tonight and Monday morning. Mainly onshore winds 5 to 15 knots.

MARINE

(Today through Friday) Issued at 403 AM PDT Sun Jun 14 2026

Gentle southerly breezes and moderate to rough seas with a low south-southwesterly swell persist across most of the coastal waters. Winds will remain fairly consistent to Monday as the seas subside. Fresh to strong north winds will develop in the northern outer waters towards the middle of the week.

BEACHES

Issued at 1230 PM PDT Sat Jun 13 2026

Long period southerly swell will continue through the weekend, especially for south and southwest facing beaches. Hazardous beach conditions are advertised, specifically for moderate to steeply sloped beaches along the Pacific Coast of the North Bay, San Mateo, Santa Cruz counties. A Beach Hazards Statement is in effect for Pacific coast beaches along the central coast and the Bay Area coast from late tonight through late Tuesday night. Be sure check beach conditions before you head out. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean!
