San Diego in May

Great time to visit

May offers excellent weather once the morning gloom burns off. Just be prepared for crowds and the highest accommodation prices of the year.

Weather

May brings warm, dry days with highs around 23°C and lows near 16°C. This is peak "May Gray" season – that marine layer can stick around until noon or even early afternoon. Once it clears, you get postcard-perfect weather with minimal humidity.

All Months

April through October delivers San Diego's legendary weather. Temperatures hover between 65-75°F with minimal rain. But these are also peak tourist months with higher prices and crowds. Summer (June-August) means perfect beach weather but also Comic-Con in July, which books up hotels citywide. Hotel rates spike to $300+ per night during the convention. Fall (September-November) might be the sweet spot. Ocean temperatures peak in September, crowds thin out after Labor Day, and hotel prices drop 20-30%. Winter brings the city's only real rain, mostly January and February. But temperatures still hit 65°F most days. Hotel rates drop to their lowest, sometimes under $150/night downtown. Spring (March-May) offers great weather with wildflower blooms in the desert areas. Baseball season starts, and the city feels energized. Avoid visiting during major conventions like Comic-Con (July) or the Rock 'n' Roll Marathon (June) unless you're participating. Everything books up and prices double.
