Is the 2026–27 "super El Niño" going to soak San Diego this winter?
Probably wetter than normal, but it is not guaranteed: NOAA gives the coast a 50–60% chance of an above-normal winter, and the last "Godzilla" El Niño in 2015–16 actually left San Diego drier than average.

King tides this winter: the dates, and why El Niño makes them matter
The highest tides of the 2026–27 winter fall on the mornings of November 23–26, December 22–25 and January 20–22, peaking at about 7.56 feet on December 24 — and El Niño stacks extra sea level and bigger surf on top of them.

What strange sea life shows up in San Diego during El Niño — and should I worry?
Warm El Niño water brings tropical visitors like hammerhead sharks, devil rays and swarms of bright-red tuna crabs; they're mostly harmless to people, but don't eat the crabs, don't handle a sea snake, and report anything unusual to Scripps.

When is the water warm enough to swim without a wetsuit?
August is the peak at about 68°F, with July and September close behind around 66–67°F. June is only 64–65°F despite feeling like summer — the water lags the air by roughly two months.

Can a hurricane actually hit San Diego?
A direct hurricane is extremely rare — the only one on record with hurricane-force winds here was in 1858 — but tropical storm remnants, heavy rain and big southerly swells are a real fall risk through November 30, and El Niño makes them more likely.

Does a wet El Niño winter mean fire season is over in San Diego?
No — El Niño's rain mostly arrives December through March, and San Diego's most dangerous fire window is fall, when Santa Ana winds hit vegetation that's driest from late September to mid-November; expect Red Flag Warnings and possible SDG&E power shutoffs until the rains actually come.

The San Diego roads that flood in the rain, and what to do if you hit one
The repeat offenders are the Mission Valley river crossings (Fashion Valley Road, Avenida del Rio, Camino de la Reina, Mission Center Road), Sorrento Valley Road at Carmel Mountain Road, and low spots in Otay Mesa — and the rule is simple: never drive into water you can't see the bottom of.

What do people get wrong about visiting in June?
That June is a sunny beach month. It's usually the grayest stretch of the year on the coast — "June Gloom" — while inland areas a few miles east are clear and hot. And the water is still only about 64–65°F.

Why is it 20 degrees hotter at my hotel than at the beach?
The marine layer — a shallow deck of cool, damp ocean air that sits on the coast and burns off inland first. The gap between a coastal and an inland neighborhood on the same afternoon regularly runs 10–20°F.
