Opinion polling in the Philippine Senate election, 2013

Opinion polling (locally known as "surveys") for the Philippine Senate election, 2013 is carried out by two major polling firms: Social Weather Stations (SWS), and Pulse Asia, with a handful of minor polling firms. A typical poll asks a voter to name twelve persons one would vote for in the senate election. The SWS and Pulse Asia's surveys are usually national in scope, while other polling firms usually restrict their samples within Metro Manila.

Candidates

There two major coalitions in this election: Team PNoy (known as the LP-Akbayan-NPC-NP-LDP Coalition until January 27, 2013), and the United Nationalist Alliance (UNA). The two coalitions used to share three common candidates, until UNA dropped them. A third coalition, the Makabayang Koalisyon ng Mamamayan (Makabayan; Patriotic Coalition of the People) share four candidates from Team PNoy. A further two more parties put up ticket of three candidates each, two parties had a ticket made up of one candidate each, and three candidates are independents that are not a part of any ticket.

These are aside from the parties that put up candidates, and may belong to any coalition. In the tables below, the colors refer to the parties, unless otherwise stated in the seat totals sections.

Graph

The result of each candidate's opinion poll (survey) result is denoted by a plot point, or a "period" (per.). The lines denote moving averages (mov. avg.) of the last three polls (each poll given equal weight) for each candidate; as pollsters may use different methodologies, it is invalid to plot each period from all pollsters as if it is a single series. Hence, a moving average is used to link all polls from all pollsters into one series. Some candidates may not appear on some polls, and these do not include candidates who are not on the final list but were included in other polls. The twelfth ranking candidate in each poll is denoted by a line, for easy reference.

Seats won

The first figure denotes the number of candidates from the party or coalition that made it to the top 12 in each survey; the figures inside the parenthesis are other candidates that made it within the margin of error. The figure of the party or coalition (except independents) the most seats is highlighted; those that outright win a majority of seats contested (7, if 12 seats will be contested) is italicized, while the party or coalition that outright wins a majority of seats in the Senate (13) is boldfaced.

Some of the totals might not add up as most slates have shared candidates.
