San Diego is preparing for a holiday weekend marked by significant waves and tropical moisture as Hurricane Marie approaches.

Labor Day Weekend Forecast: San Diego Braces for High Surf and Humidity

As the Labor Day weekend approaches, San Diego residents are bracing for a mix of unsettled weather and tropical influences. The city is expected to experience higher humidity and large waves thanks to the distant but powerful presence of Hurricane Marie.

The weekend will begin with a cooler and less humid Friday, offering a brief respite before the tropical moisture moves in. Temperatures will range from the 70s and 80s along the coast to the low-100s in the deserts, providing a comfortable start to the holiday.

Tropical Moisture and Isolated Showers

The main weather story for the weekend revolves around Hurricane Marie which is currently churning in the Pacific. While the storm is expected to track farther west and not directly impact San Diego, its tropical moisture will still affect the region. This moisture could bring isolated showers and a slight chance of thunderstorms late Saturday into Sunday.

Rainfall totals are expected to be light, with most areas seeing between a few hundredths of an inch to a quarter of an inch. However, the humidity levels will be noticeably higher, making the air feel muggy and uncomfortable for many.

High Surf Advisory and Coastal Flooding

One of the most significant impacts of Hurricane Marie will be the large waves expected to hit San Diego’s beaches. A High Surf Advisory and Coastal Flood Advisory will be in effect from 6 am Saturday until 11 pm Tuesday. Waves of 6 to 10 feet are expected along south and southwest-facing beaches, while west-facing beaches can expect waves of 4 to 7 feet.

The combination of high surfhigh tides and strong rip currents will create dangerous swimming conditions. Additionally, astronomical high tides could lead to coastal flooding and beach erosion with the greatest impacts expected on Monday.

High Tide Times

Here are the expected high tide times and heights for the weekend:

  • Saturday 6 feet at 4:48 pm
  • Sunday 6.3 feet at 6:03 pm
  • Monday 6.7 feet at 7:03 pm
  • Tuesday 6.8 feet at 7:54 pm

Temperature Outlook

Despite the tropical influence, temperatures will remain seasonable. Along the coast, expect 70s and 80s while inland areas will see mid-80s to low-90s. The mountains will stay in the 70s and the deserts will be in the 90s offering a bit of relief from the humidity.

Looking ahead to next week, seasonably warm weather is expected to continue. Monsoon moisture is also likely to return, keeping humidity levels elevated and bringing a chance of showers particularly in the mountains.
