We present X-ray observations of the northern outskirts of the relaxed galaxycluster A1413 with Suzaku, whose XIS instrument has the low intrinsicbackground needed to make measurements of these low surface brightness regions.We excise 15 point sources superimposed on the image above a flux of $1\times10^{-14}$ \fluxunit (2--10keV) using XMM-Newton and Suzaku images of thecluster. We quantify all known systematic errors as part of our analysis, andshow our statistical errors encompasses them for the most part. Our resultsextend previous measurements with Chandra and XMM-Newton, and show asignificant temperature drop to about 3keV at the virial radius, $r_{200}$. Ourentropy profile in the outer region ($> 0.5 r_{200}$) joins smoothly onto thatof XMM-Newton, and shows a flatter slope compared with simple models, similarto a few other clusters observed at the virial radius. The integrated mass ofthe cluster at the virial radius is approximately $7.5\times10^{14}M_{\odot}$and varies by about 30% depending on the particular method used to measure it.
