If you're interested in winter sports, the best time to go to Lake placid is November. That's when the ski slopes typically open. In November prices are also still low and the weather is a little warmer than in January or February, when it drops under 30F. If you’re more in the mood for hiking and warm weather, then August is one of the best times to visit Lake placid. Accomodations are affordable and temperatures in their mid 70s. If you decide to visit during the summer, try to avoid the "Horse show" week (late June/Early July) as well as the Ironman competition in mid-september, unless of course you're interested in one of these events. That's when prices for hotels and vacation rentals surge the most.
