“Beware the Ides of September” has a nice ring to it, and if you have spent today bracing for something ominous, we regret to inform you that you are two days late and also generally misinformed. We should know — we double-checked before publishing this, and we were wrong at first too.
Here at bayflorist.com, we deliver flowers, not history lessons, but every once in a while the calendar hands us something too good to pass up. So: what the Ides of September actually is, why it is not what most people think, and what we would rather you actually pay attention to this week — the weather, which is doing something genuinely worth noticing.
📜 What “the Ides” Actually Means
The Ides was not a specific date on the Roman calendar — it was a marker that floated depending on the month, tied originally to the full moon. In March, May, July, and October, the Ides landed on the 15th. In every other month, including September, it landed on the 13th. Which means the actual Ides of September already happened this week, two days before this post went up, entirely without incident, exactly as it does every single year.
The 15th feels like it should be the answer for every month, because the one Ides anyone actually remembers — the Ides of March — happens to fall on the 15th. That single famous date did a lot of quiet damage to general Roman calendar literacy for the next two thousand years.
🗡️ Why March Gets All the Drama
The reason “beware the Ides of March” became a permanent piece of the language and “beware the Ides of September” did not is refreshingly simple: Julius Caesar was assassinated on March 15th, 44 BC, a soothsayer had apparently warned him the date was coming, and William Shakespeare turned the whole thing into one of the most quoted lines in English literature about 1,600 years later. September’s Ides, by contrast, has no togas, no senators with hidden daggers, and no Shakespeare. It just quietly happens every year, correctly landing on the 13th, and nobody writes plays about it.
So if you did feel a faint sense of dread today, we can say with real historical confidence: that is not the Ides talking. That is just a Tuesday.
🍇 What Is Actually Happening This Week (the Part Worth Noticing)
While we were all misremembering Roman calendar trivia, the actual news around the Bay Area this week is that we are deep into one of the best two-week stretches of weather the region gets all year. We wrote about the coast-to-coast version of this split in The Post-Labor Day Split a couple of weeks back — the short version, for anyone who missed it: while the Pacific Northwest is packing summer away for good, the fog here is finally pulling back, and September is quietly the payoff month locals wait for all year.
This is also, not coincidentally, crush season across Sonoma and Napa — the grapes are coming off the vine right now, wine country is at its most photogenic and its most fragrant, and the golden late-afternoon light that shows up this time of year is exactly the kind that makes every backyard dinner and every vineyard weekend look like it was shot for a postcard. If dahlias are still your thing — and around here, they very much still should be — ours are having one of their best weeks yet, something we get into in more detail in our piece on why the dahlia is San Francisco’s official flower.
🌸 So, No Reason to Beware Anything
No senators, no soothsayers, no daggers. Just a genuinely lovely stretch of Bay Area September — clear skies, grapes coming in, dahlias still going strong, and absolutely nothing to be cautious about except maybe underestimating how good this week actually is compared to literally any week in August. If you are looking for a reason to send flowers today and “it is a beautiful, historically uneventful Tuesday” feels a little thin, we would remind you that we already covered exactly this problem in our guide to sending flowers for absolutely no reason at all. No reason required. No Ides to beware. Just a very good week for flowers.
