Residents of southwestern California are experiencing a weather rollercoaster, with November bringing a deluge that approached record highs for the month, now followed by a forecast of dry, warmer conditions. According to the NWS San Diego, after a wetter-than-normal November, the region's weather pattern is shifting with the return of the Santa Ana winds and a rise in temperatures expected early next week.

Highs are forecasted to cool slightly below average on Wednesday with coastal low clouds spreading inland onto the seaside slopes of the mountains, as reported by the National Weather Service San Diego. "Gusty north winds will develop through and below the Cajon Pass on Wednesday afternoon with more widespread and stronger northeasterly winds for Wednesday night," the NWS San Diego adds, with gusts potentially topping around 45 mph. Despite the recent cooling trend, inland temperatures are set to climb 10 to 15 degrees above average by next Tuesday.

The forecast also indicates a deepening of the marine layer, which could bring patchy drizzle to coastal regions overnight into early Wednesday. Areas like Orange, San Diego, western Riverside, and southwestern San Bernardino counties should anticipate a rapid deepening of the marine layer, which may result in light showers with a less than 10 percent chance of measurable rainfall, according to the latest update from the NWS San Diego.

Along the coast, beachgoers should be cautious as a Beach Hazards Statement is in effect from this evening through Friday morning. "Astronomical high tides are forecast to occur each morning Wednesday through Friday, threatening minor tidal overflow and beach erosion," says NWS San Diego. High surf conditions, reaching up to 4-6 feet, especially in San Diego County, may amplify the impacts during these periods. For those planning marine activities, no hazardous conditions are expected through Saturday, offering a brief respite amidst the dynamic weather changes.
