Series Of Storms, Massive Waves
The sun returns to some extent with partial clearing Sunday afternoon. A few showers may continue in the Santa Cruz Mountains, however. We’ll get clipped by the next weather system overnight with any rainfall focused in the north—and it looks to remain light. A stronger system will then come in on Tuesday with wind & rain. More on that in the extended section below. In the meantime, major swells (waves!) will be impacting our coastline for the next couple of days. It will be dangerous near the ocean with huge breakers, beach erosion, and coastal flooding. Stay out of the water.
AIR QUALITY: Good to Moderate
**HIGH SURF ADVISORY**
… in effect now until Sunday 4PM for the entire immediate coastline of Santa Cruz and Monterey counties, including the Monterey Bay.
*Expect large westerly swell with breaking waves of 20 to 26 feet, including breakers near 30 feet at favored spots such as Mavericks.
*Dangerous swimming and surfing conditions and localized beach erosion. Large waves can sweep across the beach without warning, pulling people into the sea from rocks, jetties and beaches. Sudden immersion in cold water can result in cold water shock even for the most experienced swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough open waters.
Inexperienced swimmers should remain out of the water due to dangerous surf conditions.
Sunday: Becoming partly cloudy. Warmer, with highs in the upper 50s to upper 60s. Clouds increase late with another chance for light rain.
***HIGH SURF WARNING***
… for the entire immediate coastline of Santa Cruz and Monterey counties, including the Monterey Bay from 4pm Sunday until 12pm on Tuesday
*Dangerously large breaking waves of 30 to 35 feet, including breakers up to 40 feet at favored spots such as Mavericks.
*Life-threatening swimming and surfing conditions and significant beach erosion can be expected. Large waves can sweep across the beach without warning, pulling people into the sea from rocks, jetties and beaches. Sudden immersion in cold water can result in cold water shock even for the most experienced
swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough open waters.
Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure.
***COASTAL FLOOD WARNING***
…for the entire immediate coastline of Santa Cruz and Monterey Counties including the Monterey Bay in effect from 4pm Sunday until 12pm
*Significant coastal flooding expected.
*Life-threatening swimming and surfing conditions and significant shoreline erosion can be expected. Numerous roads may be closed, and some critical infrastructure will be inundated. Large waves can sweep across the beach without warning, pulling people into the sea from rocks, jetties and beaches. Sudden immersion in cold water can result in cold water shock even for the most experienced swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough
open waters.
Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth.
Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure.

Extended: Stormy weather returns early Tuesday as a relatively strong cold front moved through the area. Moderate rain and gusty winds are likely. Some minor wind damage will be possible. There will also be a slight chance of thunderstorms. Cooler weather will follow with partial clearing late in the day. Dry weather then continues into Christmas Day and early Thursday. Rain chances return late Thursday into Friday.
