A sublime Sunday sunrise at Whaler's Cove, on the south side of Pigeon Point. (sound on)

Just a bit of sunrise color upon calm waters. 11/29/2025

Escapees? A couple wild turkeys in the hills above Pescadero on the run. 😊

Here is this morning's image of the "footprint" of Tule Fog in the Central Valley and adjacent valleys. Similar conditions, with low visibilities, are expected tomorrow. Please slow down and give yourself extra time to get to your destimations safely.

Just the 28% waxing crescent moon picking up a hint of rosy color from the setting sun. 11/25/2025

Surfers and spindrift at Steamers in Sana Cruz. 11/23/2025

Tule fog (i.e., radiation fog) forming in the Delta and the west side of the Sac and San Joaquin Vlys from the perfect recipe of moist ground, clear skies and light winds. Note the "curl" in the fog (top center) as the Sutter Butters protrude above. (6:36 am pst, GOES NT-Physics)

A tiny (3%) sliver of the crescent moon above the Pillar Point radome.

In response to seeing the term Atmospheric River misused and overused.

In response to questions about how meaningful a wet start (ggweather.com/seasonal_rai...) is to the entire rainy season, I looked at the correlations between the Jul-Nov rainfall to the final Jul-Jun totals. There are some huge differences.

Yes, hawks eat earthworms. After it rains, earthworms come to the surface and are a relatively easy high-protein breakfast.

For Pigeon Point Lighthouse's 153rd birthday here are a few of my favorite pix. 11/15, 2025

Overall, today's storm was fairly typical for mid-November in the Bay Area, and as the first one-inch event, a good bookmark for the beginning of our winter rainy season. A great soaker, with a minium number of locallized problems.

8:16 am. A Narrow Cold-Frontal Rainband (NCFR) moving onshore through San Francisco and approaching Half Moon Bay with localized moderate-heavy rain.

A subtle Sunday sunset at Surfer's Beach. 11/9/2025

Sandhill Cranes are back to their wintering area in the Delta west of Lodi. These are truly magnificent birds. 11/3/2025

I've put some of my favorite pix of the San Mateo coast into a FREE downloadable 14-month calendar. View on your device, print it out, or whatever! Enjoy. I just ask that you find some way to pay it forward. Click here: ggweather.com/coastside.pdf

Lots of of atmospheric distortion to the setting sun, with an elevated Green Flash on top. Half Moon Bay, 11/2/2025

The Austrailian Bureau of Meteorology (BOM) has implemented a new methodology for identifying ENSO events. Instead of using only Niño 3.4, they are computing their Relative Niño Index relative to the entire tropical Pacific SST anomalies. See www.bom.gov.au/news-and-med...

What's your "ideal" climate? www.sfchronicle.com/weather/arti...

Not all La Niñas (or El Niños) are created equal! Precip from the last two weak La Niñas was extremely different. (Last year did not qualify as a "historic" La Niña). The screaming message is that past ENSO events have very little predictive value. Caveat emptor!

A peek-a-boo orange sherbet sunset at Pigeon Point Lighthouse. 10/15/2025

Conditions were too good tonight, with clear skies and a late moonrise, to not chase the Milky Way. It was definitiely worth the trip. Pigeon Point Light Station State Historic Park, 10/11/2025. (Tech notes: Nikon D850, 22mm, f3.2, iso 800, single 20 sec exposure)

NOAA has forecast a weak La NIña. But with that comes great uncertainty. The last 2 weak La Niña winters show vastly different outcomes. (Last year did not reach the 5-month threshold to officially be a La Niña). There are no simple teleconnections looking at ENSO events alone.

Tonight's full Harvest Moon rising over the Coast Range east of Half Moon Bay. 10/6/2025

"Moon in the sky like a big pizza pie, that's amore"; at least for my fellow selenophiles. After being blocked as it rose, tonight's 98.5% full moon rose above the fog and called to me. 10/5/2025

Pelican photo-bombing the sunset. Half Moon Bay. 10/3/2025

The Rockies are ablaze with color right now! This is from this morning west of Boulder. 9/30/2025

In going back through last night's pix, I found a shot from a different angle of the Milky Way (and about a gazillion stars) at Pigeon Point Lighthouse. 9/20/2025

A fiery sunset as high clouds from the remnant of former Tropical Storm Mario moved in and the low clouds moved out! 9/17/2025

Pillar Point wearing its solar halo! 9/15/2025

While Sea Surface Temperatures Anomalies (SSTA) edge toward La NIña territory in the tropics, the north Pacific continues to warm. Here's a comparison of Pacific SSTAs in mid-Sept for the past 7 years.

Go outside and breathe in some fresh air. Can you smell the sweet slightly pungent smell of this morning's rain on the soil? Enjoy.

Pre-sunset lenticular over the Coast Range east of Half Moon Bay this evening.

A quick snap of Pigeon Point Lighthouse before the fog started rolling in. 9/6/2025

The fog in Half Moon Bay chased me south to Pigeon Point to catch the Full "Corn" Moon (aka Harvest Moon) rising over the Santa Cruz Mtns. 9/6/2025
