Peru is rich in geographical variation due to its diverse regions that boast unique microclimates. When it comes to the coastal capital of Lima, however, there are just two distinctive seasons: winter and summer. Though Lima is, in fact, a desert, its generally mild weather can be owed to the metropolitan city’s location: just intimate enough with the Humboldt Current to offset the beating sun with hovering clouds and mist, yet guarded from tropical rainfall thanks to the Andes Mountains that stand between the urban center and the Amazon rainforest.  

The ideal time to visit Lima? Right before the uncomfortable humidity of summer (September to October) or at the tail-end of it (April to May). If you can’t beat the heat (or grey), take a look at the following perks and challenges of each season, average temperatures, and what to pack.

Summer in Lima (November-March)

Towards the end of November, warm temperatures and clear skies gently wake Limeños (Lima residents) from their fog-filled slumber. The relief and excitement to see the sun is palpable city-wide as life returns to color. 

In December, just when things are beginning to heat up, the Peruvian school year comes to an end. While the traffic thins, streets and shops are still thick with pedestrians. Summer also signifies the high tourism season, so expect packed beaches and thriving nightlife. 

Whether to escape the crowds or chase the sun (or perhaps both), many of the city's wealthier residents head to the pristine beaches of Peru just an hour’s drive south of Lima or a one-hour flight north. In a city of nearly 10 million, this seasonal migration barely makes a dent, though swanky AirBnBs and dinner reservations will become more available. 

February is the hottest month during Lima’s summer and relative humidity levels hover between 80 and 90 percent. Coincidentally, the hours in the day seem to increase with leisurely lunches, picnics, and sunset viewings along the high coastal bluffs seeping well into the night.

What to pack: Bathing suit, sunglasses, brimmed hat, sunscreen, and surfboard (if you have one) to enjoy the beach; walking or running shoes to take advantage of the picturesque malecon on fresh summer mornings or evenings. Light layers are a must as nighttime temps drop slightly (64 F / 18 C) yet remain comfortable enough for a T-shirt or dress and thin cover-up.

Winter in Lima (June-August)

With minimal rainfall (after all, Lima is an urban desert) and temperatures that hover around 60 F (16 C), winter in Lima is comparatively mild and manageable for those accustomed to frigid climates. However, for those who suffer from Seasonal Affect Disorder (SAD) the low-hanging fog and minimal daylight of wintertime in Lima are plenty harsh.

It’s not uncommon to experience a streak of misty and hazy days while visiting Lima in winter. Called la garúa, moist sea fog is essentially trapped in the urban landscape creating a persistent haze. Brushed by chilly sea breezes, coastal districts like Magdalena, Miraflores, and Barranco will feel the coldest.

Since the tourism levels are comparatively low at this time of year, you can relish in discounted accommodations and promotions. It’s also a fine time to cozy up with some of Peru’s renowned soul food to warm your body and soul. The coffee scene in Barranco, undoubtedly Lima’s hippest district, is enough to make anyone face the chill and take a stroll. 

Just remember that Peru’s Independence Day is celebrated every July 28 and 29, and many establishments will remain closed. 

What to pack: Heavy winter jackets are not necessary when visiting Lima, however pants, knits, sweatshirts, and windbreakers are ideal for the frigid and damp air driven by the relative humidity.
