What you are reading: 8-year historical averages from the ERA5 reanalysis, not a forecast. A month that is historically 90% clear can still be overcast on your specific trip. For this week’s actual forecast, see the live Palm Desert page. Both can be true at once: “historically strong in this month; this particular week is not.” We label which is which.
