Those winds and the weather pattern is exactly the same here every single year due to the unique geography of the LA basin and the deep ocean upwelling current. Upwelling currents are rarely in contact with a desert that also varies between onshore and offshore wind patterns. The atmospheric change that happens after each solstice causes turbulent weather every year. The fires this year were due to the first large shift in the ebbing flows that happened to not carry any moisture in the shift. The proceeding pattern a few weeks later brought the region’s first rain of the pattern.

As an all-weather daily cyclist commuter for years, I hatted wind far more than rain, but I know these patterns better than a farmer’s almanac.

The severity of the shifting patterns was not even extraordinary for the area. There are warnings in the area about the high winds and warnings for tractor-trailer trucks because the winds often are powerful enough to overturn a 53’ van trailer even on seemingly regular days.

There are tremendous temperature and humidity differences in a very small geographic distance. The LA basin is a bowl of very high mountains with one side slot open to the desert and half of the bowl open to the Pacific.

This area is actual one of the least altered by patterns of weather because ocean upwelling is an enormous stability sink. The ocean waves are eroding more, but massive Australian sand imports that happened in the past have stopped thus masking the cause of erosion. Winters are a little warmer, but that is not very noticeable as a negative.
