New Relic: Page load time varying widely from day to day

We recently introduced New Relic SPA monitoring on our web app. It's been over two weeks, and the data that we are seeing on New Relic is ... confusing:

enter image description here

The initial page load time is varying vastly, with no apparent correlation with other data (we collect traffic data using MixPanel, and the data doesn't show any particular relation between traffic spikes and performance). enter image description here

The application has a Rails backend, PostGreSQL DB, EmberJS frontend and we use Heroku and AWS S3 to server the static frontend site.

Could someone with experience with monitoring tell me what this could be a symptom of? And possibly how to fix this?

On New Relic, we're using SPA monitoring with default settings
