Marine Weather and Tide Forecast for La Mirada, CA

.SHORT TERM (TDY-THU)...08/238 PM.

Weak Santa Ana conditions associated with weak to moderate offshore flow across the region will persist through Wednesday under a quite strong ridge aloft for this time of year. The result will be dry, warm, and breezy conditions with widespread highs in the 70s to mid 80s with the warmest valleys nearing 90 degrees.
These types of temperatures may bring increased concerns for heat illnesses for vulnerable people or those who are outside for a prolonged period of time. The dry air mass and long nights this time of year will support temperatures dropping off quickly in the evening, especially where winds drop off. The ridge begins breaking down with offshore flow weakening or reversing onshore Thursday, kicking off a decent cooling trend.

Peak wind gusts in the typical Santa Ana Wind corridor and other wind prone areas such as the Santa Lucias will generally be 20 to 40 mph peaking each night to early afternoon through Wednesday. A Wind Advisory continues for the Santa Lucias with marginal wind advisory possible for the most prone Santa Ana wind areas of Ventura/Los Angeles County. Fortunately, fire weather concerns are still limited due to the significant rainfall we experienced earlier this season.

.LONG TERM (FRI-MON)...08/239 PM.

Seasonably warm conditions are anticipated this weekend with night to morning low clouds potentially returning to coastal areas along with afternoon to evening breezy onshore to northwest winds.

Rainfree conditions look to continue well into next week. There is a 30-40 percent chance of a strong ridge rebuilding overhead into the middle part of next week with weak to moderate Santa Ana conditions at times. In this scenario, widespread highs in the 70s to mid 80s would return for most coasts and coastal valleys. If the ridge is weaker or offshore flow doesn’t materialize (40-50 percent chance), more seasonably warm temperatures (60s and 70s)
would be common.
