Currently in San Francisco — September 25, 2023: Mild, warm Monday

The weather, currently.

The air quality has finally improved after many days of erroneous predictions. Are you relieved? And more importantly: will it last? While the wildfires that caused the smog still persist, it looks like the winds may keep the worst of the haze away from SF for a while now.

Monday will be cloudy in the morning, with the sun arriving midday as the temperature heads up toward 70. Winds will also pick up, with gusting up to 20mph. Overnight, lows will be around 60 — and there is a slight chance of drizzle! What a novel way to start a new week.

What you need to know, currently.

Fall is here, and so far the trees are not disappointing this year.

My new favorite fall leaf-peeping guide is Explore Fall, which daily auto-generates a 7-day forecasted fall-colors map on almost a neighborhood scale based on weather, soil moisture, sunlight, and citizen science observations for the entire lower 48 states (sorry, no Canada yet).

Here in Minnesota, I tested out the algorithm on a few hikes this weekend and the leaves were stellar. It’s that time of year where the leaves seem to change almost hour-by-hour, so if you have a chance to get out there, don’t miss it.
