San Juan in February: 29°C / 84°F afternoons, 22°C / 72°F nights, and the dry season's first clear month.
Pack for the dry season's first clear month. NOAA NCEI's normals for San Juan's airport give February 83.8°F by day and 71.8°F at night, the lowest normal low of the year, with about seven nights at 70°F or below. Rain falls to 2.58 inches from January's 4.07, and only about seven days bring a tenth of an inch or more; of the twelve months, only March is drier. That makes February a month for walking. The Park Service opens the forts at 9am and sells a $10 pass good at both for 24 hours, and the Forest Service keeps the PR-191 corridor into El Yunque free, with no reservation. Dress for Old San Juan's pastel streets by day, in butter yellow, pistachio and peach on white, and keep a cardigan for the terrace after dark.
February is San Juan's clear month: pastel cotton for the painted streets, trainers for a day on foot, and a cardigan for the coolest nights of the year.

For 84°F days in the second-driest month of the year: NOAA NCEI's normals give February 2.58 inches of rain, and only about seven days bring a tenth of an inch or more. Eyelet cotton lets air through its holes, wide straps stay put on the long walk up to El Morro, and butter yellow matches the painted façades of Old San Juan. Button the pistachio cardigan over it after sunset.

The swell season is still running: Discover Puerto Rico puts the peak surf from October to April, on the north and west coasts, so read the Weather Service's rip-current risk before you swim. A halter that ties at the nape stays put in a wave, an open back dries fast in a dry-season sun, and pale peach warms the white and yellow above it.

For the coolest nights of the year. February's normal low, 71.8°F, is the lowest of any month on NOAA's airport normals, and about seven February nights fall to 70°F or below. A short-sleeve knit takes the edge off a breezy terrace without the bulk of a jacket, buttons over the sundress, and pistachio sits between the butter yellow and the peach.

Long sleeves for the evening, when the air cools toward 72°F, and for keeping the sun off your arms by day. Lace at the collar and the flared cuffs dresses up dinner in Old San Juan, the tie front adjusts over the jeans or the swimsuit, and white goes with every pastel here.

Long legs for a day out of the city and for the cooler evenings. A cropped wide leg keeps air moving at 84°F and clears a wet step, and bleached, light denim stays cooler in the sun than dark indigo. Wear them with the lace blouse for dinner and with the trainers on the PR-191 corridor into El Yunque, which the Forest Service opens from 8am to 5pm.

A dry month is a walking month. At El Morro and San Cristóbal the Park Service warns of uneven, steep and slippery surfaces and asks for sturdy footwear, and at El Yunque the Forest Service asks for shoes with traction because the forest is wet and mossy. A thick rubber sole covers both, and leather and suede stay clean in a month when only about seven days bring real rain.

Worn across the body, a zip-top bag stays shut and in front of you in a crowd and leaves both hands free on the forts' ramps. Raffia is light for a full day out, holds a phone, sunscreen and a card for the Park Service's cashless $10 pass, and suits a dry month: only about one February day brings half an inch of rain or more.

For the beach and the pool only. Rubber flip-flops pack flat, rinse clean of sand and dry in minutes, and butter yellow matches the sundress. Change into the trainers before you leave the sand: a flip-flop slides on the forts' ramps and comes off on a crowded street.
Butter-yellow eyelet sundress · off-white trainers · raffia crossbody · peach halter one-piece underneath, flip-flops in the bag. El Morro when it opens at 9am, then the beach after lunch.
White lace-trimmed blouse · light-wash cropped jeans · pistachio cardigan over the shoulders · off-white trainers · raffia crossbody. Sunset at about 6:24pm mid-month, then dinner in Old San Juan as the night cools toward 72°F.
A suggested look — white lace-trimmed ruffle blouse, light-wash cropped wide-leg jeans, pistachio short-sleeve cardigan, off-white chunky trainers.
Warm, dry and cool at night. NOAA NCEI's 1991–2020 normals for San Juan's Luis Muñoz Marín airport give an average February high of 83.8°F (28.8°C) and a low of 71.8°F (22.1°C), the lowest normal low of any month, with 2.58 inches (66mm) of rain. Measurable rain falls on about 15 days, but only about seven bring a tenth of an inch or more, against about ten in January. Only March is drier. About seven nights fall to 70°F or below. Sunset moves from about 6:17pm on 1 February to 6:30pm on the 28th.
A butter-yellow eyelet sundress, a pale peach halter one-piece, a pistachio short-sleeve cardigan, a white lace-trimmed blouse, light-wash cropped wide-leg jeans, off-white chunky trainers, a raffia camera crossbody and butter-yellow flip-flops. That covers the forts in the morning, a beach afternoon, a day at El Yunque and dinner in Old San Juan. The cardigan matters more than it looks: February has the coolest nights of the year.
Yes. The Forest Service says the PR-191 recreational corridor is free and needs no reservation, open from 8am to 5pm, with numbers managed because parking is limited. El Portal, the visitor centre, opens daily from 8am to 4pm and charges $8 for visitors 16 and over; its holiday closures fall in November, December and January, not February. The Forest Service posts trail closures on its status page and asks for shoes with traction, because the forest is wet and mossy. Wear thick-soled trainers and long jeans, and keep the cardigan for the drive back. Rideshare apps cannot collect you at the gates, so plan the return before you go.
Late February, for longer evenings: sunset comes at about 6:17pm on the 1st and 6:30pm on the 28th. Mid-February, for a long weekend: Presidents' Day, Monday 15 February, is a federal holiday, and Valentine's Day falls on the Sunday before it. If you can push into March, NOAA NCEI's normals make it drier still, with 2.18 inches of rain against February's 2.58.
February is drier and a touch warmer by day. NOAA NCEI's airport normals give February 83.8°F (28.8°C) by day and 71.8°F (22.1°C) at night, against January's 28.4°C and 71.9°F, with 2.58 inches of rain on about 15 days against 4.07 inches on about 18. Days with a tenth of an inch or more fall from about ten to about seven. January carries the end of the Christmas season, Three Kings Day and SanSe, which our January guide covers; February packs lighter on rain gear and heavier on walking shoes.
Light cotton by day, a layer after dark, and often a bag made on the island. Concalma, the fair-trade label Matilsha Marxuach founded in San Juan in 2006, has its bags sewn at a women's cooperative in the mountain town of Utuado, and its shop is at 621 Calle Ernesto Cerra in Santurce. At 72°F after dark, a February evening is cool enough for a knit over your shoulders.
