The National Weather Service in San Diego is forecasting a warming trend that is set to begin in the region. According to their latest update, San Diegans can expect higher temperatures over the weekend, with highs on Sunday being 5-10 degrees above the norm. The warming is likely to continue into Monday, with temperatures forecasted to be 10-15 degrees above average levels. This information, outlined in a bulletin published on the NWS San Diego website, indicates a shift in weather patterns for Southern California residents.

Delving deeper into the week, the Area Forecast Discussion by NWS San Diego details that alongside the rise in temperatures, periods of weak to locally moderate Santa Ana winds are expected, peaking on Tuesday; such conditions elevate the heat, ushering a semblance of summer in the early days of winter, the forecast notes a winter morning, that then slides into a summer-like early afternoon with highs in the low 80s, before retreating into a fall evening. The skies are expected to remain clear, with light winds and neutral pressure gradients, which will facilitate the development of a weak sea breeze this afternoon.

The forecast also mentions a small chance of patchy dense fog in some coastal areas near the coast tonight and again Sunday night. But for those inland, clear skies will permit a slow ritual of sun worship, as temperatures steadily climb and lend themselves to a warmth that seems eager to remind us of the impermanence of seasons. However, the Santa Ana winds, though moderate, are a force to be reckoned with, gusting potentially up to 45 mph in certain wind-prone areas—painting a different picture, one not purely of warmth and light, but also of a dry, piercing breath from the deserts.

For maritime interests, no hazardous marine conditions are expected through Thursday, providing a window for sailors and coastal goers to enjoy the gentler sides of Pacific oscillations. Likewise, beach hazards appear to be minimal with high tides hovering around 6 to 7 feet, promising a serene beach experience for those scanning the horizon where the water meets the sky, as reported by the NWS San Diego. While the upper high pressure is anticipated to shift east, and the forecast for the later part of the week carries a hint of uncertainty concerning the possible weakening or breakdown that could result in a cooling trend, at least for the next several days, the narrative will be one of sunshine and unusually warm December days.
