San Isidro in October

Lima's weather stays remarkably consistent year-round, hovering between 60-75°F. The so-called winter months from June to September bring more clouds and drizzle, but temperatures barely budge. This actually works in San Isidro's favor — the gray skies create a cozy atmosphere for long restaurant meals and golf rounds without scorching sun. Summer (December to March) brings clearer skies and warmer temperatures, perfect for walking the malecón or dining on outdoor terraces. But here's what matters more: avoid major Peruvian holidays when restaurants close and traffic becomes unbearable. Independence Day in late July shuts down the city for days.
