When you're making travel plans months in advance, you should look for information on climate rather than weather. Climate data provide long-term averages for temperatures, rain, snow and sunshine. You can even find out how many clear versus cloudy days to expect during your stay. 
Researching an area's climate will tell you what the weather conditions are most likely to be when you visit. If you were thinking of visiting a Tucson timeshare in February to bask in the hot, desert warmth, you might want to rethink things. The average temperature in Tucson in February is a chilly 55 degrees! (Shown above left: Starr Pass Golf Suites.) If you want to toast in the sun, you'll have to head for the Virgin Islands where the average February temperature is a toasty 79 degrees. (Shown below right: Bluebeard's Beach Club & Villas.)
My favorite site for climate information is www.weatherbase.com which provides up-to-date climate information on 16,439 locations worldwide. A great vacation planning aid, the site provides annual as well as monthly data. You can find out everything you ever wanted to know about a site's temperature fluctuation: average high, average low, highest recorded, lowest recorded, average number of hot days (90+), average number of warm days (70+), average number of cold days (-32) and average number of frigid days (-10).
When you're within a week to 10 days of your vacation, that's when you want to check the weather. Weather forecasts give you short-term predictions that focus on current weather conditions in the area. Check the climate of your timeshare vacation site when you plan your trip; check the weather just before you leave.
