In this guide you will find the best times to have an outdoor event in the pacific northwest, why you should consider an outdoor gathering, and our favorite vendors that can help take your plans from concept to execution. 

Why You Should Consider an Outdoor Event 

After a year of isolation, there is a strong desire to bring events back and gather in person. It makes sense! The pandemic is finally slowing down, we’ve seen tremendous improvements in infection rates much thanks to vaccines. However, we aren’t quite out of the woods yet. As event professionals we must design events that have our guest’s safety in mind, outdoor events can help you provide the opportunity to meet again with less risk. In fact, according to the White House “less than 10 percent of documented transmission, in many studies, have occurred outdoors.”  

Hosting outdoor events will greatly reduce transmission risk and create a safer environment for your guests. Almost any event can be transformed into an outdoor event. The most common outdoor events include company picnics, team building events, concerts, and even weddings. 

Best time for Outdoor Events In Seattle 

The Pacific Northwest certainly has earned the reputation for being the rainiest place in the country but don’t let this stop you from hosting your next event here. There are an average of days of sunshine in Seattle. The trick is to time your event during the dry months. The best time to have an outdoor event in the region is between May – September, there is less rain during these months and temperatures averaging in the 70s. 

Create a Backup Plan

In events it’s always smart to have a plan B, and outdoor events and picnics are no exception. Outdoor events are subject to weather. Planning during optimal months greatly reduces the chances of a rain storm interrupting your plans but it’s always important to create a backup plan. 

Consider looking for a venue that has an alternative location such as an indoor venue you can switch to in the case of inclement weather. If the venue does not have an indoor location, consider renting a tent. If weather makes a turn for the worse you may need to postpone the event, or relocate to an indoor location! Leading up to the event, monitor weather, let it guide your choices.
