It’s National Weather Person’s Day today, which is mainly celebrated in the US. But here at Seasonal Heights in London we think that this is a great thing. One of the key features of the Seasonal Cities app is the weather page for each city, which selects venues from the guide according to the realtime forecast in that destination. To help celebrate this climactic occasion, we bring you five of the best picks from the weather pages of the app for today. So whether you are putting on the layers in New York or stripping off under a hot sun in Sydney, let’s hear it for the folks who keep you jolly under that brolly.

BARCELONA – 9C/SUNNY WITH CLOUD – SIGHT

Els Encants

Barcelona bargain hunters were not amused by plans to destroy the city’s original flea market, so it was integrated into the city’s newest barrio, District22@, by adding a geometric reflecting roof that ripples over an interior coiling over three floors. It may look new but the bric-a-brac and antiques remain the same – the best items are on the ground floor. Every Monday, Wednesday, Friday and Saturday. www.encantsbcn.com.

NEW YORK – MINUS 2C/SNOW – SHOP

Patricia Field

Counterculture icon Field is to street style in New York as the Chrysler is to architecture. Yes, she provided the costumes for Sex and the City, but her oeuvre is so much cooler than that, as is her boutique on the Bowery (she used to sell hand painted T-shirts by Basquiat before he was famous). Come for crazy iPhone covers and a whole lot of leopard print. Favourite item: the black leather Dark Knight baseball cap, complete with tiny horns. www.patriciafield.com.

PARIS – 3C/SUNNY WITH CLOUD – EAT

A.Noste

Chef Julien Duboué has sold Dans les Landes in the 5th to create this convivial triple southwestern flavoured eatery near the Bourse. On the ground floor, snack on Basque taloa (stuffed corn pancakes) from a food truck or sample delicious tapas along shared tables (fried squid and assorted duck things are favourites). Upstairs, the style is more gourmet with spit-roast meats and inventive bistro dishes. Favourite table: The communal table on the ground floor. www.a-noste.com.

ISTANBUL – 16C/CLEAR NIGHT – DRINK

Zelda Zonk (pictured)

You can pay the £5 entrance fee for the Galata Tower. Or you can ride the elevator to strike-a-pose Zelda Zonk and sink a sunset G&T for a few dollars more. This rooftop bar takes its name from the check-in pseudonym of Marilyn Monroe (she once booked an LA-New York flight under that name). Zelda pairs movie star pretentiousness with prices to match. Favourite drink: there are less expensive places to sip an Efe Organic Rakı, but who’s counting? www.gradivahotels.com/zeldazonk.php.

SYDNEY – 22C/CLEAR NIGHT – SLEEP

Pullman Quay Grand Sydney Harbour

At this luxury hotel in East Circular Quay, you pay for the vistas. Situated between Sydney Harbour and the Royal Botanical Gardens, the one and two-bedroom apartment-style suites pair harbour or garden views with generous balconies and a simple, modern aesthetic. The recently relaunched Q Dining restaurant features a micro-seasonal menu and a bespoke open charcuterie kitchen. Request to sit at table number seven. Favourite room: 1,002 is a one-bedroom harbour view suite with spectacular views. www.pullmanquaygrandsydneyharbour.com.
