Weather forecasts affect life of many people and are used by the general public on a daily basis. However, they are not perfect and there is an uncertainty associated with the current weather forecasts, and the users should be aware of this uncertainty. Previous research analyzes the perceptions, uses, and interpretations of uncertainty of Spanish undergraduate students. The present study continues with this research line, but in this case, we investigate the degree of confidence and communication preferences of students enrolled in three Meteorology-related subjects taught at two universities in Spain. In this regard, we evaluated to what extent students trust in the current weather forecasts, and analyzed how students are aware of the uncertainty associated with the forecasts considering different lead times. In addition, we assessed how students value the forecast of several weather elements, as well as the students’ preferences for deterministic versus nondeterministic forecasts under two weather situations, with different degree of complexity in the forecast communication. A Google Form questionnaire was developed in order to address these issues. The survey was conducted in the academic year 2018-2019, and 101 participants anonymously filled out the survey. Participants were enrolled in three different subjects taught in the Degree in Marine Sciences at the University of Alicante, and the degrees in Environmental Sciences and Physics at the University of Valencia. Results show that students have a well-formed opinion of weather forecasts, both regarding confidence and in relation to the trend found in the current weather forecasts towards less accurate forecasts for larger lead times. Regarding students’ preferences for deterministic versus nondeterministic forecasts, a significant majority of participants have a preference for weather forecast which incorporates some kind of uncertainty compared to those who prefer single-valued (deterministic) forecasts. Comparing our results with those found in previous studies conducted to date in different countries and contexts, similar outcomes are observed in general, but some differences are highlighted as well in the current study.
