The National Weather Service (NWS) is forecasting elevated tides across Southern Marin from July 9 through July 16, bringing the potential for minor, nuisance flooding in low-lying coastal areas.
Late-night and early-morning high tides are expected to range from 6.38 to 7.2 feet. While these water levels are not expected to produce significant flooding, residents and visitors may encounter water covering portions of roadways, parking lots, trails, and other shoreline areas during the highest tides.
The National Weather Service has issued Coastal Flood Advisories for:
- Bayside Marin: July 9–16
- Pacific Coast of Marin: July 11–15
Current forecasts indicate that high winds and rainfall are not expected to coincide with these tides, reducing the likelihood of more significant coastal impacts. Additionally, the projected tides remain well below the 8.4- to 8.6-foot king tides experienced in January 2026.
Dry Lightning Potential Being Monitored
In addition to elevated tides, the National Weather Service is monitoring the potential for dry lightning across the region beginning late this weekend into early next week.
Forecast confidence remains low, and the exact timing, location, and coverage of any lightning activity are still uncertain. However, dry lightning can ignite vegetation fires when little or no rainfall reaches the ground, particularly during the summer fire season.
Southern Marin Fire District personnel are monitoring weather conditions and remain prepared to respond should wildfire activity occur.
Safety Tips
Residents are encouraged to remain aware of changing weather conditions and take simple precautions during periods of high tide:
- Avoid driving through flooded roadways or standing water.
- Use caution near waterfront parking lots, trails, and shoreline access points that may temporarily flood.
- Allow extra travel time if traveling during late-night or early-morning high tides.
- Stay informed by monitoring forecasts and official weather updates.
The Southern Marin Fire District will continue to monitor conditions and provide updates if forecasts change or additional advisories are issued.
