NEW YORK (TheStreet) -- The temperature is heating up here in the Berkshires and for many here and across the U.S., this means a time to escape the day to day office life and enjoy some welcomed rest and relaxation.

While many are counting down to the time when they can replace their desk chairs with beach chairs, for others, the introduction of the summer months can present a number of attractive investing opportunities.

Within the ETF universe there are a number of products that may prove exciting to watch over the next few months.

PowerShares Dynamic Leisure & Entertainment Portfolio

(PEJ) - Get Report

Investors can profit as friends and family escape the workplace for the fun in the sun. PEJ is a unique, consumer-focused ETF product designed specifically to track the companies responsible for providing individuals with the food, fun, and entertainment that define summer vacation.

The fund's top holdings include

, and


(DIS) - Get Report

. Despite its niche focus, PEJ's index is relatively well-diversified. The fund's 10 largest positions account for less than half of its index.

iShares Gold Trust

(IAU) - Get Report

As we have seen so far this year, it is difficult to predict when and where the next bout of market turmoil will originate. Given this uncertainty, investors will want to make sure that they maintain a level of defense when it comes to navigating the market the next few months. Gold, bonds, and dividend-paying equities will come in handy when it comes to weathering turmoil.

Another precious metal ETF to keep an eye on will likely be the

iShares Silver Trust

(SLV) - Get Report

. This shiny, industrious metal has run into headwinds since falling from near record highs. In the near future, it will be interesting to see if volatility persists.

iShares MSCI EMU Index Fund

(EZU) - Get Report

The first half of 2011 has been inundated with concerning international stories and events including the bloody political turmoil in the Middle East, and the devastating Pacific earthquake.

Meanwhile, in Europe, ongoing sovereign debt issues have continued to generate headlines and raise investor ire. As vulnerable nations including Spain, Ireland, and Greece work to battle economic headwinds, this region will likely be one to keep an eye on. Risk tolerant investors looking to track the developments in this corner of the developed world will want to keep EZU on the radar.

EZU boasts heavy exposure to troubled nations such as Spain, Italy, and Portugal. However, with Germany and France headlining the geographic breakdown, the fund may be able to offset some of the region's volatility.

iShares Dow Jones Transportation Average Index Fund

(IYT) - Get Report

Rising energy prices have been on the minds of many as they prepare for the summer travel season. Interestingly, however, oil's ascension has had only limited effect on the companies underlying the Dow Jones Transportation Index so far.

Over the most recent three month period, IYT has managed to outpace the broader

SPDR Dow Jones Industrial Average ETF

(DIA) - Get Report

by a comfortable margin.

Although the impact has been limited so far, it will be interesting to see if energy prices will affect the plane, train, and delivery industry as summer presses on. IYT's performance may also provide investors with insight into the state of the consumer. Companies like

First Trust Dow Jones Internet Index Fund

(FDN) - Get Report

The Internet industry will be on investors' minds over the next few months as they attempt to profit from the hot social media industry. Following the successful IPOs of





(YNDX) - Get Report

, many have begun to question whether we are in the midst of a new Internet bubble. This debate will continue to rage in the months ahead as the markets seek to uncover clues regarding the futures of Zynga, Twitter, and Facebook.

FDN is an attractive, well-diversified product for investors looking to access the Internet's popularity. Rather than exposing investors to volatile, newly IPOed firms like LinkedIn, this fund combines exposure to weathered online veterans including
