Ready to discover incredible and affordable destinations for summer? I've researched trends and prices around the globe to find these 10 spots ideal for a great summer vacation that won't break the bank. From the off-season Caribbean to a stunning South Pacific island, there's a destination for every vacationer at a great price this coming season.

San Francisco and Sonoma County, California

San Francisco is typically not the first city that comes to mind when you say "affordable," but thanks to new flight routes and lower hotel prices, the city and nearby wine country make for a great—and affordable—summer getaway this year.

Flights: Round-trip airfare from New York is well under $400 for the summer months—CheapTickets.com found average air bookings to be $392 and StudentUniverse found fares as low as $279. Allegiant Air is debuting nonstop flights to Sonoma from Phoenix and Las Vegas. And Alaska Airlines already offers direct flights from Los Angeles, Orange County, Portland, San Diego, and Seattle. Alternatively, check Oakland and San Jose airports for even cheaper prices from more regional destinations. Keep in mind that because of their proximity, you can easily fly into any of these airports to reach either San Francisco or Sonoma.

Accommodations: HotelTonight found the average daily room rate for San Francisco hotels to be $205 per night and Sonoma County hotels to be $199 per night. Priceline.com also found average hotel prices to be moderate at $215 per night, with rates starting at $86 per night for a three-star hotel in July and August. If you're really looking to save, consider the highly rated USA Hostels San Francisco, with rooms starting under $60 per night.

What to Do in Summer: There are plenty of free and inexpensive ways to see San Francisco and Sonoma. With temperate summer weather, biking and walking tours are an ideal way to see the city on a budget. Bike the Golden Gate bridge and explore Lands End (part of the Golden Gate National Recreation Area) or charming Sausalito located on the other side of the bridge; walk around the vintage shops and cafes in Haight-Ashbury; or catch a Giants game at AT&T Park.

Sonoma, which is only 30 miles north of the Golden Gate Bridge, has over 425 wineries, 100 organic farms, and 50 miles of coastline. It makes for a great addition to any Bay Area vacation. Rent a bike and camping gear through California Touring Bikes and explore its multi-day route ideas, starting at $105 per day including camping gear. Or opt for a free self-guided vineyard tour through Vineyard Adventures, which offers walks of seven different wineries in the area.

Caribbean

Yes, June marks the beginning of hurricane season, but that ensures an abundance of off-season deals. If you're looking for a paradisiacal destination and willing to risk the weather, the Caribbean should be on your list for summer. Thanks to some geographic luck, the Southern Caribbean islands are more protected from hurricanes—although we still recommend going with travel insurance. Look at Aruba, Curacao, Barbados, and Trinidad and Tobago for a safer bet if you want to avoid rough weather.

Flights: StudentUniverse found round-trip flights for the summer months under $350 from New York for the following islands: Puerto Rico, Bahamas, Trinidad and Tobago, Bermuda, Aruba, U.S. Virgin Islands/St. Thomas, Dominican Republic, and Jamaica.

For example, at Frenchman's Reef & Morning Star Marriott Beach Resort in St. Thomas, for $257 per night you get room accommodations, a night kayaking tour or catamaran sail trip, admission to St. Thomas Coral World Ocean Park, and access to private Morning Star Beach. Curacao and Trinidad hotel deals can be found well under $150 per night, with the Floris Suite Hotel in Curacao starting at $89 per night and Trinidad's Coblentz Inn Boutique Hotel from $105 per night. Check out other hotel deals on St. Maarten, Turks & Caicos, and Nassau Paradise Island.

Cruises: MSC Cruises has summer promotions on many of its sailings from Miami to the Caribbean on MSC Divina, with packages starting as low as $279 per person for three and four night cruises, and $499 for seven night cruises.

What to Do in Summer: The same things you can enjoy the rest of the year, just at a fraction of the cost; snorkeling, scuba, and fishing tours are all much cheaper this time of year.

Check out the Cayman Island's "Summer Only in Cayman" promotion for deals up to 20 percent off peak season prices. Come summer Curaco offers music festivals like Viva La Musica Latina and Amnesia Curacao.

Toronto, Canada

A strong U.S. dollar makes Canada extremely affordable and accessible for Americans right now.  Summer is a great time to visit Toronto, since it's a time of favorable weather and plenty of outdoor events.

Flights: CheapTickets.com found average round-trip flight prices from New York to be $163 for the summer months and priceline.com deemed August to be the cheapest month for flights. Toronto is also a short flight from the Northeast and Midwest, making it a quick, international weekend getaway.

Or, opt to stay at the trendy HI-Toronto hostel, with starting rates under $40 per night. The hostel also has bike rentals and free city tours to make the most of your budget.

What to Do in Summer: Summertime in Toronto is great for foodies. There's the Taste of Toronto and Toronto's Festival of Beer, as well as South by Southwest's counterpart, North by Northeast (NXNE). Toronto is less than a two-hour drive to the Canadian side of Niagara Falls; Algonquin Provincial Park and Blue Mountain also make for great outdoor day trips from Ontario's capital.

Martha's Vineyard, Massachusetts

Experience a quintessential New England summer on this well-known Massachusetts island. This summer, you won't even need to break the bank to enjoy this popular summertime destination.

Ferries: Ferry access from Hyannis, Wood's Hole, New Bedford, New York City, and New Jersey means you can avoid summer traffic and enjoy your ride to the island. Once you're on the island you can get anywhere you need to with a bike, taxi, or Uber, so you don't need to worry about a car.

Flights: If you do want to fly, Cape Air, Delta, American Airlines, and JetBlue fly direct to the island from most major Northeast hubs. Flying is much faster than taking a ferry, and you can find cheap flights midweek and on non-holiday weekends.

Accommodations: Lark Hotels just opened a brand new location in Oak Bluffs, Summercamp, with affordable opening rates starting at $149 and a 10/20/30 deal ($10 credit at "Camp Canteen" store, 20 percent off rooms, and $30 credit for future Lark Hotels stays) for its first season. It's also worth checking out vacation rentals if you're traveling with a group, since that will score you extra amenities at a lower price than hotels. Just keep in mind that most rentals require a full week's stay, typically from Saturday to Saturday.

Things to Do in Summer: Get outside and enjoy the island's golf courses, bike paths, and beaches. The towns of Edgartown and Oak Bluffs have great bars, restaurants, and shopping.

Lake Atitlan, Guatemala

Summer is the undiscovered perfect time to visit Lake Atitlan. Since summer is the region's wet season, discounts are abundant—but unlike in many other Central American spots, Lake Atitlan's rainy season is softened by plenty of sunshine.

Flights: StudentUniverse found low fares from New York to Guatemala City for $337 round-trip during the summer months. Priceline.com reported the cheapest fares from New York in the month of August. Low-cost carrier Spirit flies direct from the U.S. from Miami, New York, Dallas, Los Angeles, Houston, Washington D.C., and Atlanta.

And enjoy authentic local food at low prices; since this area is popular with backpackers, tourist prices tend to remain affordable.

Asheville, North Carolina

Asheville, named one of SmarterTravel's 10 Best Outdoor Towns in America, is a perfect summertime destination with outdoor activities and easy access from the East Coast and South.

And since it's still an up-and-coming destination, prices haven't yet escalated out of reach of bargain travelers.

Flights: StudentUniverse found low fares starting at $266 round-trip from New York for the summer months, and Priceline.com reported average round-trip airfare to be lowest from New York in August.

The Great Smokey Mountains National Park and town of Hot Springs are both a short drive away.
