Noter fra rejsende om San Diego i august
My family visited San Diego in August after living in Singapore for a year and when people complained about the humidity, even my younger sister gave them the "you softies don't know what you're talking about, why I have to walk 15 miles to school in the jungle, uphill both ways!"

Regulars explain the region's forecast confusion with a specific structure: four distinct zones each day - coast (coolest), inland (at least 10 degrees warmer), mountains (more rain, occasional snow) and desert - so a single citywide number always hides real variation. Our row backs the pleasant coastal read this month, 24.6C over 16.3C nights, with rain minimal at 6.1mm across under a day. Regulars call this one of the best months overall, generally clear, dry, sunny and warm, with the occasional Santa Ana condition pushing dry desert winds and temperatures into the 80s Fahrenheit even on the coast. The sea is cooling toward 19.2C, on the cold side for a swim by regulars' own standards. The record: humidity 75 percent, 10.2 hours of sun, a 14.3 kph wind and AQI 63.
Regulars call September the best month here and give two reasons that have nothing to do with the air. The ocean is at its warmest of the year - they put it in the low seventies Fahrenheit and our column reads 20.3C - and the crowds go home after Labour Day while the weather carries on unchanged. Our row gives 25.8C reading as 27C over 19.4C nights, with 5.5mm of rain in the whole month and 11.1 hours of sun. The marine layer that shapes June has gone by now. Humidity is high at 77 percent but the sea breeze at 14.9 kph handles it. The record: a dew point of 16.7C and AQI 53.
May Gray and June Gloom are the local names for a marine layer that can sit over the city all day in late spring, and regulars say it weakens through June and is usually gone by July. What replaces it is a daily cycle rather than a season: cloud overnight, burning off through the morning and clear by about noon, with the cloud rolling back in off the ocean in the evening. Some years the layer does hang on into July, which they call unusual. Our row is as maritime as that sounds - 24.7C days and 19.4C nights, five degrees apart - with 1mm of rain, 13 hours of sun and a 20C sea. The record: humidity 78 percent, a 14.6 kph wind and AQI 51.
San Diego forum regulars keep December's range wide but genuinely mild: “highs will be somewhere between 50 and 80 and the lows between 35 and 55,” with a more typical read “temps in the 60s°F during the day” and chilly mornings and evenings. Rain totals for the whole month run modest — “about 1.3 inches” — but nobody can tell more than a week or 10 days out whether a given trip lands wet or dry. Standard packing: jeans with a long-sleeve tee or light jacket by day, a proper coat once the sun drops, and regulars specifically say to leave the umbrella at home since rain is infrequent enough not to be worth the space. Our record: 17.6°C days, 9.8°C nights, 6 rain days and 59.7mm of rain — mild and mostly dry, matching the “generally sunny and cool, occasional wet week” read.
