PAGASA’s Mactan International Airport climate normals cover 1991–2020. The table shows lower average rainfall in March and April than in July and October, but every month has rainfall. Normals describe long-term averages for the airport station; they cannot tell you the weather or sea conditions on your travel dates. Check current PAGASA forecasts and warnings before outdoor or marine plans.
The long-term pattern at the airport station
PAGASA’s 1991–2020 normal table for Mactan International Airport lists average monthly rainfall of 60.9 mm in March and 55.6 mm in April; the same table lists 210.6 mm in July and 207.6 mm in October. Those figures help compare months in the historical record. They do not mean a given week will be dry or wet, and an airport station does not represent every microclimate around Cebu.

A normal is not a forecast
PAGASA defines climatological normals as averages over a standard multi-decade period. Daily weather, tropical cyclones and local conditions can differ from those averages. Use the station table for broad context and the current PAGASA forecast and warning products for decisions close to departure.
Weather and sea plans are related—but not identical
A sunny view from the hotel does not establish that a boat trip or dive is suitable. Conditions offshore, official advisories, local authority restrictions and operator decisions all matter. Ask your provider how they make the departure call and what happens to your booking if conditions change. The sea-day guide sets out the questions to ask.
Pack for changeable days
Plan breathable clothing, sun protection, a light rain layer and a dry way to protect medicines, documents and electronics. Keep some flexible indoor time in a short itinerary. This is practical packing advice, not a forecast for any month.
How to read the Mactan normal table
In PAGASA’s 1991–2020 table, the Mactan International Airport station records an annual rainfall normal of 1,685.0 mm and 138 rainy days under PAGASA’s stated definition. Monthly rainfall ranges from 55.6 mm in April to 210.6 mm in July in that table. The monthly mean temperatures range from 26.8°C in January to 29.4°C in May. These are station averages across the reference period, not a forecast for a particular year or resort.
A rainy day in the table means at least 1 mm recorded during its defined 24-hour period. Monthly rainfall amount and rainy-day count answer different questions: one is total recorded water, the other how often the threshold was reached. Neither tells you whether rain fell all day, at your hotel or during your planned boat trip. Open the original PAGASA table ↗
Use the right weather information at each stage
Months ahead, use the climate normal to set broad expectations and choose how much flexibility to build into the trip. In the week before departure, consult PAGASA’s forecast products for the relevant area. Near a boat or dive departure, check current advisories and the operator’s decision. A climate average cannot replace an operational go/no-go assessment.
PAGASA lists public forecasts, tourist-area outlooks, tropical cyclone bulletins and shipping forecasts among its services. Use the product suited to the decision, and follow local authorities and the operator for the exact route. PAGASA forecast services ↗
Build a weather backup into the itinerary
Choose one flexible block that can move if outdoor conditions change: a rest period, a meal near your accommodation or a heritage/craft plan whose access you have confirmed. Keep important documents, medication and electronics protected from water, and carry sun and rain protection appropriate to your own needs. These preparations help across varied conditions; they do not predict the weather.
For marine plans, ask the provider what triggers a change or cancellation and how you will receive notice. Keep the written booking terms and a way to contact the operator. See sea-day planning and a flexible three-day itinerary.
What the monthly pattern means for a visitor
The PAGASA table’s lower average rainfall in March and April compared with July and October can help you think about flexibility when choosing dates. It does not create a reliably dry season: the table records rainfall in every month, and short local showers can differ from the monthly total. Even a month with a lower normal can include a wet day during your stay.
Treat the numbers as a long-term baseline rather than a promise when comparing resort dates, planning a boat trip or packing. For near-term choices, use the current PAGASA outlook and ask the activity provider how it handles conditions. The airport station is a reference point; weather at sea and at another part of Cebu may differ.
