Unlike Cyms for instance, phals don't need that big of a temperature difference. While cyms need a 10°C difference, phals only need a few degrees difference for a few weeks. Also from what I've read on internet, it's not the day/night temp difference that initiates spiking, buy rather a general cooling down on day and night temperatures. Rosie C, many of my phals set spikes during the summer as well. I don't know what kind of summer you had, but in my area of France august was much cooler than june and july. That could explain the spikes...
