You can do a bit more with metro-e style NIDS... those have the layer2
tools to do proper testing.

Dragonwave was contacted as well. No determination yet though.

Backpressure from the switches in terms of flow-control can show
as latency on dragonwave links.
Disable any QOS features on the dragonwave if you are using them.

No routers between, just switches.

Could the routers at each end be the limiting factor? What is
their CPU utilization when the link is loaded? What happens to
latency if you stress the link at 200 Mbps with a speed test?
Those radios should be able to do close to 400 Mbps all day long
with no latency.

Yes it’s a horizon compact
Bandwidth of the unit is 400mbs
Bandwidth usage between 150-200mbs during peak hours.
No QOS
Yes during non-peak hours its sits at 1ms
SNR 35.00 dB
From our prtg graphs this issues has started end of September and
latency has gotten worse during peak times as we have deployed
more 450 gear to that tower.
I currently have HAAM enabled on the link and it stays at 256qam
unless we have some bad weather.

So it's a Horizon Compact?
What is the total bandwidth, and what percentage are you using?
Have you set up any QOS? 180 ms sounds like a lot; especially
when ours are typically less than 1 ms.
-38 is right in the game. What are the other parameters besides
signal level?

We have a dragonwave that has latency issues that coincide
with traffic peak times. As our traffic peaks so does that
latency at 180ms. Any ideas that could cause this?
Signal is -38
