Look on the bright side: At least summers are predictable... On our winter trips we've had swings of 50 degrees in a week's time (seriously, lows in the 30s and highs in the 80s in one trip!), and the weather forecast wasn't accurate until about 48 hours out which left us rather blindsided because we hadn't packed for near-record lows! The summer forecast, on the other hand, has very little variation; you'd pack the same for 85 degrees as for 95, and you can assume the sub-tropical chance of rain every day knowing that it very rarely lasts more than a short time.
