Batten down the hatches, San Francisco. The National Weather Service has a fairly clear message for locals: breezy conditions are here to stay through the weekend with a slight cooling trend before things start heating up again. According to a recent report by NWS San Francisco, we’re in for a “subtle warming trend” starting Saturday, and temperatures are set to rise above the norm by the end of the month.

In the immediate term today and tonight, expect fair weather but keep a sweater handy since temperatures will dip slightly below usual for this time of year. However, there's a heads-up for those in wind-swept locales along the coast and valleys: the gusts might turn a stray spark into a wildfire, so be cautious. "It won't take much for grasses to light up and spread quickly while the winds are breezy," the National Weather Service cautions.

It seems the wind will dial back for the week ahead, starting Saturday, but not enough to lose the ‘breezy’ tag just yet. As we sit under this transitioning weather pattern, NWS San Francisco suggests now is the time to “prepare before we have anything more to worry about.”

The aviation outlook seems consistent with the terrestrial forecast, with coastal stratus causing visibility issues along the coast and bay area airports this morning. The gusty west wind is expected to keep things interesting for pilots, bringing in periods of IFR conditions before clearing up later in the day. For those planning to catch a flight, it would be wise to check in with your airline ahead of time for any weather-related delays.

Lastly, mariners aren’t being spared either. The marine forecast by the National Weather Service warns of "hazardous marine conditions" due to strong northwesterly winds, prompting small craft advisories and even gale warnings in some zones. This brew of choppy seas and gusty winds will stick around until at least Monday. Boaters, note and ensure you're geared up for some challenging conditions.
