If you have the luxury of planning your trip, you’ll experience the best weather in April, then July through October. Pack an umbrella for November through February visits. June gets the least amount of sun thanks the fog that settles over the coast. July and August are super hot.
Keep your business attire based on your company’s requirements but plan to dress more casual in the evenings. Even on the hottest of days, plan for cooler evenings so that means light jackets and wraps.
