The Longitude festival at Marlay Park kicked off sucessfully on Friday night with Stormzy as the headline act, while The Weeknd are due to take care of things on Saturday.

Longitude has developed a lovely reputation of being a festival for the young ‘uns (age 18-25, approximately) on Friday and Saturday nights, with some of the best international acts giving it socks, while Sunday is reserved for the oldies.

After Saturday things will wind down, almost to a dangerously low heart rate, with the banjo-wielding Mumford and Sons finishing things off for the weekend.

The line-up is heavier on the hip-hop and R&B side of things than it has been in previous years, and UK grime legends Wiley and Skepta will undoubtedly deliver phenomenal sets.

The latest additions to the bill are Irish acts All Tvvins, Barq, Wyvern Lingo, Brave Giant and Columbia Mills, while Pusha T is stepping in to replace Earl the Sweatshirt, who cancelled his set, on Saturday. It's an overtly male line-up but if you can, catch Dua Lipa at 5pm on Friday and Sigrid at 3.30pm on Saturday for your pop fix.

The official Longitude app (for Android and iPhone) is now available to download and you’ll be able to create your own schedule for the weekend, explore the festival site map, and stay up-to-date on any festival news over the weekend.

As one of Dublin’s biggest outdoor music festivals, there will be extra security measures in place.

Are tickets still available? Weekend tickets and day tickets are now all completely sold out.

What time does it kick off at? Gates open at 1.30pm each day, with the first acts on stage around 2pm.

How do I get there? Traffic will be heavy around Marlay Park so guests are advised to use public transport to get to and from the event. If you are driving, take the time delays into account and where possible, carpool to limit the number of cars coming into the area.

The closest Luas stop is Dundrum and shuttle buses will bring festivalgoers from there to Stonemasons Way, near the concert entrance. The shuttle buses will leave every 30 minutes from 1pm and return tickets are €8 online or €10 return when purchased on the day. See bushiredublin.net for more details.

Will I need to bring ID? Yes. All bars onsite will operate a "challenge 21" policy, where you will be asked to prove your age if you look under 21. You may be asked to prove your age with photo ID or you will be refused admission.

All festivalgoers are advised to bring photo ID (passport, Garda Age Card, driver’s license, and under-18s are advised to bring either a school or college ID plus a colour copy of an in-date passport).

No unaccompanied under-16s are allowed at the festival. Under-16s require a ticket to the event and they must be accompanied by a ticket-holding adult, parent or guardian, over the age of 18.

What about booze? BYOB? Absolutely not. There will be a very strict no-alcohol policy implemented on all public transport and private buses travelling to the venue and if you arrive intoxicated you will not be allowed in. No alcohol or drinks are permitted into the venue, with the exception of up to 500ml of soft drinks in a sealed plastic bottle.

And security? In what is now the norm for large music events, only small bags measuring no larger than A4 (21cm/8.27in by 29.7cm/11.7in) will be permitted at the event. Bags will be searched at the entrances and the organisers have asked that patrons do not bring a bag to avoid long queues. There will be no cloakroom on site. Festivalgoers will be searched on entry, including a full-body pat down and/or use of hand-held metal detectors.

Banned items include: fold-up chairs or shooting sticks, umbrellas, selfie sticks, flares/fireworks, laser pens, megaphones/air horns, aerosols, spray cans, smoke and gas canisters, glass, drones, Chinese lanterns, sound systems, unofficial tabards/high-vis vests, professional cameras with detachable lens, recording equipment or Go Pros, or excessive amounts of cigarettes.

Illegal or unidentifiable substances are also banned, as are “legal highs”, herbal highs and any nitrous-oxide systems.
