Insider timing tips
- •San Diego's 'June Gloom' and 'May Gray' phenomena mean coastal fog can significantly impact morning and early afternoon conditions, particularly from May through July.
- •While summer (July-August) offers the warmest ocean water, September and October often provide superior beach weather due to less fog and lingering warmth, with slightly lower crowds.
- •The 'low season' in San Diego is not truly cold; even winter months offer mild temperatures suitable for many outdoor activities, though rain chances increase.
- •Avoid visiting during major school holidays (Spring Break in March, Christmas/New Year's in late December/early January) if seeking lower prices and fewer crowds.
